Clinical Definition of Lipid Profile

The lipid profile test is a combination of tests conducted together to check for any risks of coronary heart disease, or as a preventive measure to check any risks depending on factors like eating habits, diet, stress, exercise and life-style related.A typical lipid profile includes the following tests:

High density lipoprotein cholesterol (HDL-C) - “ good cholesterol”

Low density lipoprotein cholesterol (LDL-C) -“ bad cholesterol” 

 LDL/HDL Ratio (calculated values)

Triglycerides

Very low density lipoprotein cholesterol (VLDL-C)

total cholesterol

Total cholesterol/HDL Ratio (calculated values)

Lipids are the fats and fatty substances that are stored in your blood and tissues and are used by the body as a source of energy. While lipids help keep the body functioning normally, lipid disorders, like high cholesterol, might lead to life-threatening conditions like heart attacks, strokes, or coronary artery disease.

A lipid profile or lipid panel is performed to measure:

Total cholesterol level

hdl cholesterol (good cholesterol)

LDL cholesterol (bad cholesterol)

Triglyceride levels

When do you expect results?

24 to 36 Hours

Why Get Tested?

The lipid profile test is carried out to check adults and children who are risk prone to high blood cholesterol value and triglycerides. This happens because of development of diabetes, high blood pressure or a heart disease. This test is also conducted as a follow up to evalute the treatment undergone and diet control programme.

Your doctor might ask you to get a lipid profile done as a regular part of a health exam. The results from this test might be used to prevent, monitor, or diagnose various medical conditions. It may also be performed to evaluate the success of various treatments, or the effectiveness of drug therapies or lipid-lowering lifestyle changes.

In adults, it is recommended that even people with no risk factors for heart disease should get a fasting lipid profile performed every four to six years. If other risk factors are present, it is recommended that the test be performed more frequently. One of the major risk factors for a number of diseases and medical conditions is a high level of low-density lipoprotein (LDL) cholesterol. 

Apart from this, other risk factors include:

Smoking

Being overweight

Unhealthy diet

Being physically inactive or not getting enough exercise

If you are a male of 45 years or more or a female who is 50-55 years or more

If you are suffering from hypertension

Having a family history of premature heart diseases

Pre-existing heart diseases

If you’ve had a heart attack 

Having diabetes or pre-diabetes

Having high HDL is considered as a "negative risk factor". Having high levels of HDL allow for the removal of one risk factor.With children and adolescents, it is recommended to get routine lipid profiles done.

 

Reason to take Lipid Profile Test

Headache, Jaw pain, toothache

Difficulty in breathing 

Nausea, vomiting, and/or general epigastric (upper middle abdomen) discomfort

Heartburn and / or indigestion 

Hypertension 

General malaise 

Pain, fullness, and/or squeezing sensation of the chest 

Sweating 

Arm pain (common in the left arm, but may be either arm) 

Upper back pain 

Preparations Needed for Lipid Profile Test

Requires Fasting
Fasting samples needs to be collected after a minimum 12-14 hour overnight fasting status.
Clear fluids like water can be consumed during this period. Do not consume beverages like tea, coffee and milk in the morning until specimen collection is completed.
In case of diabetics on oral or injectable hypoglycemic agents, please consult your physician about continuing with these medications prior to specimen collection."

You will be required to take a number of precautions before the test is performed. You should:-

Not eat high-fat foods the night before 

Not drink alcohol, and 

Not exercise strenuously before your test

Your doctor might ask you to fast before the test, which means that you cannot eat or drink anything except water for 9 to 12 hours before the test. You are usually allowed to take your medicines in the morning of the test, with water. While fasting is not always necessary, it might be recommended. Your doctor can inform you about any additional precautions that you need to take before the test. Make sure you inform them about:

Any health symptoms or problems you’re having

Family history of heart health

Medications and supplements you’re taking

What does the test detect?

Cholesterol levels are measured in milligrams (mg) per deciliter (dL) of blood. The normal ranges are as follows: 

LDL: 70 to 130 mg/dL (the lower, the better)

HDL: more than 40 to 60 mg/dL (the higher, the better)

Total cholesterol: less than 200 mg/dL (the lower, the better)

Triglycerides: 10 to 150 mg/dL (the lower, the better)

If your results are outside the normal range, you might be at a higher risk of strokes, heart diseases, etc. On receiving abnormal results, our doctor may order some additional tests like a blood glucose test for diabetes, or a thyroid test to see if you have an underactive thyroid.

 

Sample Required?

Specimen type: Serum (Blood Sample) , 

Specimen collection procedure : Venipuncture - Collection of blood from a vein, usually from the arm.

How do you understand this result?

Reference RangeInterpretation
Total cholesterolless than 200 mg/dL (lower numbers are better)
HDL: “good cholesterol”greater than 40 - 60 mg/dL (higher numbers are better)
VLDL2 - 38 mg/dL
LDL: “bad cholesterol”70 - 130 mg/dL (lower numbers are better)
Triglycerides10 - 150 mg/dL (lower numbers are better)

Inference: The ideal values are different for people without coronary artery disease or other risk factors than for those with known coronary artery disease, diabetes, or high blood pressure. The recommended values for adults are different depending on the above risk factors.

‘*A Reference range is a set of values which helps the healthcare professional to interpret a medical test. It may vary with age, gender, and other factors. Reference ranges may also vary between labs, in value & units depending on instruments used and method of establishment of reference ranges’
