What does lipemic serum indicate?
Lipemia is defined as visible turbidity in serum or plasma samples due to the presence of lipoprotein particles, especially chylomicrons. The most common cause of turbidity is a high concentration of triglycerides [1,2].
What is a normal lipemia index?
Common wavelength ranges are approximately 570 to 600 nm for hemolysis and 660 to 700 nm for lipemia, with many instruments assessing 2 or more wavelengths in these ranges.
What does it mean when the patient’s specimen is lipemic?
Lipemia refers to an abnormally high concentration of lipids in the blood. The lipids that cause the greatest interference in laboratory testing are large lipid particles, particularly lipoproteins and chylomicrons.
What can cause lipemic serum?
The most common likely causes of elevated lipemic index were lipid-containing intravenous medications (fat emulsion for parenteral nutrition; propofol) and diabetes mellitus (mainly type 2). Table 1.
How is lipemia treated?
Centrifugation. A recommended procedure for treating lipemic samples is centrifugation using ultracentrifuge which effectively removes lipids and allows measurement of large number of analytes (42,43). However, due to the high cost, this equipment it is not available in a large number of laboratories.
What tests are affected by lipemia?
Conclusion: Lipemia causes clinically significant interferences for phosphorus, creatinine, total protein and calcium measurement and those interferences could be effectively removed by ultracentrifugation.
How does lipemia affect CBC results?
Q: What CBC parameters are affected when the specimen is lipemic? A: Lipemia in a blood specimen used for clinical evaluation can cause significant interference with obtaining accurate test values. Lipemia creates turbidity of a sample and is a result of the accumulation of lipid particles.
How are lipemic samples treated?
A recommended procedure for treating lipemic samples is centrifugation using ultracentrifuge which effectively removes lipids and allows measurement of large number of analytes (42,43). However, due to the high cost, this equipment it is not available in a large number of laboratories.
What are the symptoms of high lipids?
Dyslipidemia is defined as having blood lipid levels that are too high or low. Blood lipids are fatty substances, such as triglycerides and cholesterol.

Outlook
- chest pains or tightness.
- dizziness.
- heart palpitations.
- exhaustion.
- swelling of the ankles and feet.
- trouble breathing.
- cold sweats.
- nausea and heartburn.
What does Lipaemic mean?
: the presence of an excess of fats or lipids in the blood specifically : hypercholesterolemia.
How do you remove serum lipemia?
Conclusions: High-speed centrifugation (10,000×g for 15 minutes) can be used instead of ultracentrifugation to remove lipemia in serum/plasma samples. LipoClear and 1,1,2-trichlorotrifluoroethane are unsuitable as they interfere with the measurement of certain parameters.
What CBC results are affected by lipemia?
A. Lipemia interferes with the accurate determination of hemoglobin, or Hb, by spectroscopy on most hematology analyzers, but it does not generally interfere with determinations (especially impedance based) of red blood cell count, white blood cell count, and platelet count.
What blood tests are affected by lipemia?
How do you get your lipids down?
The first ways to reduce your lipid levels are (1) eat less fat, (2) exercise regularly and (3) lose weight if you weigh too much. If you smoke, stop smoking. If these steps don’t lower your LDL level enough, your doctor may have you take medicine to take the fat out of your blood.
What diseases are caused by lipids?
Lipid metabolism disorders, such as Gaucher disease and Tay-Sachs disease, involve lipids. Lipids are fats or fat-like substances. They include oils, fatty acids, waxes, and cholesterol. If you have one of these disorders, you may not have enough enzymes to break down lipids.
How does lipemia affect hemoglobin?
Lipemia interferes with hematology tests by the following mechanism by light scattering. This affects the following results: Hemoglobin and hemoglobin-related indices: Results in falsely increased absorbance readings of hemoglobin, causing a falsely high measurement.
How can I lower my lipids naturally?
Advertisement
- Reduce saturated fats. Saturated fats, found primarily in red meat and full-fat dairy products, raise your total cholesterol.
- Eliminate trans fats.
- Eat foods rich in omega-3 fatty acids.
- Increase soluble fiber.
- Add whey protein.
How do you reduce lipids in your blood?
What foods cause high lipids?
Foods With Lipids
- Beef Fat. Beef fat, also known as beef tallow, is almost entirely made of saturated fats.
- Poultry Skin. Chicken and turkey are generally quite healthy.
- Heavy Cream. When fresh milk is processed, a lot of the fat is removed and combined into heavy cream.
- Butter.
- Soft Cheese.
- Bacon.
