Lipemic samples are patient specimens that have a higher fat content in them, so their blood is a little more milky, thicker. Whereas, usually when you spin down whole blood, it will look like this. It has yellow, clear serum or plasma on top of the red cells. This is plasma here on top of the red blood cells.

What causes a lipemic specimen?

The most common cause of lipemia is that the patient is not fasting and has eaten close in time to the blood draw. This effect is most dramatic when the patient has consumed a meal with high fat content. However, nonfasting on its own usually does not result in enough lipemia to significantly impact laboratory tests.

What are two reasons for a lipemic specimen?

After hemolysis, lipemia is the most frequent endogenous interference that can influence results of various laboratory methods by several mechanisms. The most common preanalytical cause of lipemic samples is inadequate time of blood sampling after the meal or parenteral administration of synthetic lipid emulsions.

What is lipemic or Lactescent specimen What causes the sample to be lipemic?

Lipemia (lactescence) is caused by increased triglycerides (usually as chylomicrons and infrequently from high concentrations of very low density lipoproteins).

What causes Lipaemic sample?

Lipaemic samples are caused by an excess of lipoproteins in the blood, creating a milky/turbid appearance that interferes with multiple biochemical tests and can even cause haemolysis of red blood cells.

What does it mean if your blood is lipemic?

Lipemia is presence of a high concentration of lipids (or fats) in the blood. When donated blood is lipemic it causes the plasma-containing products to have a milky appearance.

How do you get rid of 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 is meant by lipemic?

Lipaemia is defined as an abnormally high concentration of lipids in the blood, usually in the form of very low density lipoproteins (VLDLs) or chylomicrons. Characteristically the blood plasma may appear white or milky in colour due to the presence of fat.

Does lipemia affect AST?

Comparison of the results of native serum, serum blank, and diluted serum with ultracentrifuged serum. In moderate lipemia (700–1000 mg/dl), as shown in Table 3, only ALT, ALP, amylase, AST, bilirubin, and uric acid are not influenced by lipemia.

What causes lipemia in dogs?

The most common disorders in dogs that result in this type of fasting lipemia are diabetes mellitus, hyperadrenocorticism, and pancreatitis. Corticosteroid therapy can also result in this type of a fasting lipemia. High triglycerides and cholesterol would be seen on a chemistry panel.

Why is lipemic sample not used in serologic testing?

The possible mechanism of interference by hemolysis or lipemia in serologic assays may be as follows: Interference with antigen-antibody reaction. Very severe lipemia may make it difficult for accurate volume measurement in assays requiring precise sample measurement. Interference with color measurement in assays.

What causes fat in my blood?

Most people have high levels of fat in their blood because they eat too much high-fat food. Some people have high fat levels because they have an inherited disorder. High lipid levels may also be caused by medical conditions such as diabetes, hypothyroidism, alcoholism, kidney disease, liver disease and stress.

What is the effect of lipemic serum in chloride determination?

First, lipemia can increase absorption of light and thereby decrease light transmittance used for spectrophotometric analysis. Second, lipemia can cause volume displacement, especially impacting analysis of electrolytes.

What does a high LDL cholesterol mean?

When you have high LDL cholesterol levels, it means you are at greater risk for cardiovascular disease like heart attack and stroke. The plaque formed by this fatty substance on the inner walls of arteries can block or restrict blood flow.

Why does lipemia in specimen cause an inaccurate hemoglobin value?

Lipemic specimens contain high levels of triglycerides consisting of chylomicrons and very low-density lipoprotein particles, which in turn cause turbidity. This turbidity interferes with light scatter and the absorption of light, resulting in a false increase of hemoglobin determinations.

What is high lipemia?

Lipemia is a measure of serum transparency. High levels of blood lipids, mostly triglycerides, increase serum turbidity.
