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)
Very low density lipoprotein cholesterol (VLDL-C)
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)
24 to 36 Hours
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:
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.
Headache, Jaw pain, toothache
Difficulty in breathing
Nausea, vomiting, and/or general epigastric (upper middle abdomen) discomfort
Heartburn and / or indigestion
Pain, fullness, and/or squeezing sensation of the chest
Arm pain (common in the left arm, but may be either arm)
Upper back pain
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
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.
Specimen type: Serum (Blood Sample) ,
Specimen collection procedure : Venipuncture - Collection of blood from a vein, usually from the arm.
|Total cholesterol||less than 200 mg/dL (lower numbers are better)|
|HDL: “good cholesterol”||greater than 40 - 60 mg/dL (higher numbers are better)|
|VLDL||2 - 38 mg/dL|
|LDL: “bad cholesterol”||70 - 130 mg/dL (lower numbers are better)|
|Triglycerides||10 - 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’
