What Does It Mean When Your Doctor Still Reviewing Your Lipid Test Results
Test quick guide
The lipid panel measures the amount of specific fat molecules called lipids in the blood. As a panel examination, it measures multiple substances, including several types of cholesterol.
The lipid console is used in both children and adults to evaluate risk of cardiovascular diseases like heart disease, center set on, and stroke.
About the Examination
Purpose of the test
The lipid console helps evaluate cardiovascular health by analyzing cholesterol in the blood. Too much cholesterol can build upward in the claret vessels and arteries, damaging them and heightening the adventure of issues like middle disease, stroke, and heart assail.
A lipid panel can exist ordered for several reasons:
- Screening: This is routine testing to determine if your cholesterol is normal or falls into a borderline-, intermediate-, or high-hazard category.
- Monitoring: If you lot have abnormal results on before testing or other risk factors for heart affliction, lipid testing can monitor the cholesterol in your claret.
- Measuring response to treatment: If you have been told to make lifestyle changes or take cholesterol medications, a lipid console tin evaluate your response to treatment.
- Diagnosis: Testing lipid levels can be role of the diagnosis of other medical weather condition, such as diseases that affect the liver.
What does the test measure?
Lipids are types of fat molecules in the blood. Cholesterol and triglycerides are two important types of lipids that are carried inside particles chosen lipoproteins.
The lipid panel analyzes your blood to measure different types of lipids:
- Total cholesterol:This measures your overall cholesterol level.
- Low-density lipoprotein (LDL) cholesterol:This blazon of cholesterol, known as "bad cholesterol," can collect in claret vessels and increase your take a chance of cardiovascular disease.
- High-density lipoprotein (HDL) cholesterol:This type of "good cholesterol" helps reduce the buildup of LDL.
- Triglycerides: Backlog amounts of this type of fat are associated with cardiovascular disease and pancreatic inflammation.
While these are the primary measurements in the standard lipid panel, some versions of the test may study boosted measurements.
When should I get a lipid panel test?
There are a number of circumstances in which it is appropriate to go a lipid panel exam. Depending on the medical context, the test may be used for screening, diagnosis, or monitoring.
Screening
Screening is looking for a health trouble before any firsthand signs or symptoms have appeared. The lipid panel can be used to identify people at high risk of cardiovascular disease before they develop issues like heart illness or heart attack.
Recommendations for cardiac screening with the lipid console vary between medical organizations. Screening may provide early on warning to forbid problems, just it tin be costly, crusade anxiety, and lead to potentially unnecessary treatments. Different groups of experts evaluate the evidence and come to different conclusions about who should get screened and how oft screening should take identify.
In adults without run a risk factors for cardiovascular disease, screening may be done near every 5 years. Bear witness is unclear almost the optimal age to first screening in low-risk patients. A doctor may recommend a start lipid exam in a person's 20s, 30s, or 40s depending on their state of affairs.
People who have one or more risk factors typically accept more than frequent screening and often have their get-go exam at a younger age. Examples of risk factors include:
- Historic period over 45 for men and fifty-55 for women
- High cholesterol on a prior examination
- Previous cardiovascular problem
- Smoking cigarettes
- Beingness overweight or obese
- Eating an unhealthy diet
- Not getting enough concrete activity
- Having loftier blood pressure (hypertension)
- Having a kickoff-degree relative who developed middle disease at an early historic period (under 55 in men and under 65 in women)
- Having diabetes or prediabetes
If you have i or more than risk factors, you lot may receive a lipid test every yr or every few years. The frequency of testing may depend on the results of prior tests.
For adults over 65, annual lipid testing is recommended by some experts. Other doctors may tiresome or stop regular screening if a patient's levels appear to be stable.
In children, screening may begin once risk factors are identified starting at the historic period of two. Follow-up testing is mostly continued at least every few years depending on examination results and risk cess.
Children without risk factors may still have a lipid panel exam before starting puberty. Some other exam may be performed afterward age 16. Changes to claret lipids during puberty tin reduce test accuracy from ages 12-16, and so the test is less often used in children of that age range who do not have risk factors.
Children who are at a high hazard of an inherited condition called familial hypercholesterolemia generally take more regular screening. Considering this condition can cause heart problems at a young age, screening is often washed at historic period 3, between nine-11, and at age 18.
While there is no firm consensus about screening with lipid tests, the tabular array below summarizes common approaches to this testing.
| Demographic Group | Risk Factors | Screening Frequency |
|---|---|---|
| Children | 1+ | Every 1-3 years starting when risk factor is identified |
| Children | None | In one case between ages 9-xi; again between 17-21 |
| Adolescents and adults | 1+ | At to the lowest degree every 5 years; frequently more frequently based on specific risk factors |
| Men age 20-45 Women age 20-55 | None | Every 4-6 years |
| Men age 45-65 Women age 55-65 | None | Every 1-ii years |
| Men and women over 65 | 0+ | Annually |
Monitoring
The lipid panel is frequently used for ongoing monitoring of cardiovascular risk after a person has had high cholesterol on a prior exam or afterwards a previous cardiac event like a middle set on or stroke.
In many cases, people who are at higher hazard of cardiovascular problems make lifestyle changes or take medications to assistance reduce that risk. A lipid console may exist used to monitor their response to treatment and adapt their treatment plan as necessary.
Diagnosis
While about lipid tests are used for screening or monitoring, they are sometimes used as function of the diagnostic process for wellness conditions that tin affect lipid levels, such equally pancreatitis, chronic kidney disease, or hypothyroidism.
Finding a Lipid Panel Exam
How to get tested
Many lipid tests are done with a blood describe in a doctor's office, lab, medical clinic, or hospital. The test is commonly ordered by your md. After beingness taken, your blood sample is sent to a laboratory for analysis.
Signal-of-care lipid testing involves a drop of blood taken from your finger that is immediately analyzed by a small device. This blazon of test is used in some clinics and at events like health fairs.
Can I take the test at home?
In that location are two chief ways that lipid testing can be washed at dwelling house:
- You take a modest blood sample and send it to a laboratory for assay.
- You prick your finger and put a small driblet of claret on a piece of paper. The paper either changes color or is analyzed past a small machine to make up one's mind cholesterol levels.
How much does the exam cost?
The cost of a lipid panel depends on where the examination is taken and if yous accept insurance coverage.
When prescribed by a medico, this type of bloodwork is normally covered past insurance, but you may yet take costs for a copay or deductible. There can also be fees charged by the technicians who draw your blood. Check with your doctor and insurance plan near the cost of the test.
Indicate-of-care testing at walk-in clinics or pharmacies often costs less than $100. Signal-of-care testing at health fairs is usually washed at no charge or very low-toll.
At-home testing kits that include the device that analyzes your blood frequently cost less than $150, although more expensive models are also available. Kits mostly allow y'all to test your cholesterol multiple times with divide test strips.

Taking a Lipid Panel Test
The lipid panel requires a blood sample.
- For laboratory testing, the blood sample is drawn from your vein with a needle and sent to a lab.
- For point-of-intendance and at-home testing, claret is drawn from your fingertip.
Before the test
For laboratory lipid testing, y'all typically must fast for 9-12 hours before your blood is drawn. This means non eating and drinking but h2o before the test.
In some cases, lipid testing without fasting is possible, but you should inquire your doctor's office in advance about whether you demand to fast and always follow any pre-test instructions you are given.
During the test
In most lipid tests, a blood sample is taken with a needle inserted into a vein in your arm. Before your blood is drawn, an elastic ring is tied around your upper arm to increase blood in the veins, and the puncture location is wiped clean with an antiseptic.
A needle blood draw may cause a temporary sting. The blood draw normally lasts for less than a minute.
Sometimes a drib of blood is collected by puncturing the pare on a fingertip. This fingerstick sample is used when a lipid panel is existence measured on a portable testing device, for example, at a pharmacy or health off-white. It involves a quick sting only fiddling hurting or bleeding.
After the test
After blood is drawn from a vein, a cotton fiber swab and/or band-aid is placed over the puncture site. You volition normally be instructed to keep this in place for an hour or more to forbid any unwanted bleeding.
This is a routine out-patient process, and you tin can typically bulldoze and return to basic activities as presently as the test is over. If fasting was required, you may want to bring something to eat for right after the test. You may exist advised to restrict intense exercise or physical activity for a few hours after the test.
Fingerstick cholesterol tests exercise not ordinarily require whatever special post-test restrictions.
Lipid Panel Test Results
Receiving test results
When a blood sample for a lipid test is taken with a needle, lab analysis is usually completed and available within a few days. Your results may exist sent to you in the mail or made accessible through an online health portal. Your medico's office may also contact y'all near your results. A follow-up appointment may be recommended to review your results and any necessary next steps.
Point-of-care and calm tests provide results within a few minutes.
Interpreting test results
The results of your lipid panel are reported for each type of cholesterol and triglycerides. These are measured in milligrams per deciliter of blood (mg/dL).
The optimal or target level for each function of the standard lipid examination are listed below:
- Total cholesterol: Below 200 mg/dL
- HDL (good) cholesterol: Higher up lx mg/dL
- LDL (bad) cholesterol: Below 100 mg/dL (For people with diabetes: Below 70 mg/dL)
- Triglycerides: Below 150 mg/dL
Values that do not see these targets may be classified equally borderline-, intermediate-, or loftier-risk. In general, higher-than-target levels of full cholesterol, LDL, and triglycerides and lower-than-target levels of HDL tin heighten the risk of cardiovascular issues.
Examination results are interpreted in the context of your overall wellness and other gamble factors. Many doctors use special hazard calculators that incorporate your test results, age, and other factors to determine the most appropriate next steps.
Connected cholesterol monitoring, lifestyle changes, and/or medications may be recommended to lower cholesterol and subtract cardiovascular risk, but there is non a universal consensus virtually when these types of interventions are optimal.
Cholesterol-lowering medications, such every bit a course of drugs called statins, are most likely to exist recommended for patients with very high LDL or elevated LDL combined with other gamble factors such as diabetes or past cardiovascular problems.
Abnormally depression levels of cholesterol are rare and normally associated with a wellness condition causing malnutrition.
Are test results accurate?
Cholesterol testing is routine and reliable. While no test is 100% accurate, conscientious laboratory procedures help ensure dependable test results. If proper examination procedures and preparation are followed, including fasting when needed, false positive or simulated negative results are rare.
Point-of-care lipid testing, which is performed on-site and not in a laboratory, has more variability than laboratory testing but still provides a meaningful reference betoken for measuring cholesterol. When point-of-care or at-home tests prove abnormal lipid levels, follow-up testing is often recommended in a certified laboratory.
Do I need follow-upwardly tests?
If you lot have risk factors for heart disease or aberrant lipid levels, repeat testing may be conducted at regular intervals in the time to come. Your doctor can recommend a schedule for future testing.
If your lipid levels are normal, you may non need echo testing for another v years unless your overall health or take a chance factors modify.
In some cases, other types of cholesterol testing, such as straight LDL testing, may exist needed if you accept high levels of triglycerides. While non included in the standard lipid panel, expanded lipid measurements, such as LDL particle testing, may be ordered. Additional types of tests, such as a cardiac stress test, may also be considered as role of an overall cardiovascular risk assessment.
If y'all take a point-of-care or at-dwelling exam that shows abnormal cholesterol levels, it is common to accept follow-up testing done past a laboratory.
Questions for your doctor about your test results
When reviewing your test results with your doctor, some questions that may be helpful include:
- What are my adventure factors for cardiovascular disease?
- What do my examination results show about my cardiovascular health?
- Take my lipid levels inverse over time?
- Practise I need any follow-up tests? When should I accept another cholesterol examination?
- Are any treatments recommended based on my examination results? What are my treatment options and their benefits and risks?
Related Tests
How is a lipid console different from a total cholesterol test?
A total cholesterol test measures all of the cholesterol in your claret sample without providing the separate results for LDL, HDL, and triglycerides included in a lipid panel.
Sometimes a total cholesterol test is used for initial screening instead of the lipid panel; however, even in these cases, it is commonly combined with an HDL cholesterol measurement to assure that you lot have a good for you proportion of "expert" versus "bad" cholesterol. Total cholesterol and HDL can by and large be measured without fasting beforehand.
How is a lipid panel unlike from a direct LDL test?
On a normal lipid console, the level of LDL is adamant based on a adding using other measurements in the panel. However, this adding is non valid if triglycerides are over 400 mg/dL. Another health conditions, such as liver diseases, can likewise touch the accurateness of calculating LDL in this fashion.
When LDL cannot be calculated from the lipid panel, a direct LDL cholesterol examination is used. Some labs automatically practise a direct LDL analysis when triglycerides are high, or your doctor may asking direct LDL measurement if you have a history of loftier triglycerides. If not, a separate claret sample may be needed for direct LDL testing.
How are laboratory and at-dwelling house cholesterol tests different?
Many lipid tests are conducted in a laboratory because it offers clearer quality control for sample collection and analysis. Notwithstanding, at-home tests are nearly as authentic if all instructions are followed.
At-home tests do not require taking blood from a vein. Instead, the blood sample comes from your fingertip. Depending on the type of calm test, you may get results immediately compared to inside a few days when lipids are measured past a lab.
Some at-home tests only measure full cholesterol, which is singled-out from the more than detailed lipid panel. The verbal measurements besides as their accurateness tin can vary depending on the brand.
For most doctors, laboratory testing is the standard, peculiarly for making decisions nearly treatment, just at-domicile tests can offer convenience for people who desire to have their cholesterol checked.
