What is a lipemic sample?
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.
What causes lipemic sample?
The most common preanalytical cause of lipemic samples is inadequate time of blood sampling after the meal or parenteral administration of synthetic lipid emulsions.
How does lipemia sample affect lab results?
How Does Lipemia Impact Laboratory Testing? Lipemia results from sample turbidity from accumulation of lipoprotein particles and can interfere with laboratory analysis by several mechanisms. First, lipemia can increase absorption of light and thereby decrease light transmittance used for spectrophotometric analysis.
Should lipemic samples be rejected?
Flood, et al.6 reported on a multicenter evaluation of Boehringer Mannheim/Hitachi 717 system and reported no significant interference on many assays from hemolysis, icterus and lipemia. The 55 methods included end-point chemistries, enzymes, therapeutic drugs and specific protein assays. Hursting , et al.
How does serum remove lipemia?
Conclusions: High-speed centrifugation (10,000×g for 15 minutes) can be used instead of ultracentrifugation to remove lipemia in serum/plasma samples.
Why lipemic sample are 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 lipemia Retinalis?
Lipemia Retinalis, is caused by hypertriglyceridemia with serum triglyceride levels typically greater than 1000 mg/dl. Multiple genes responsible for triglyceride metabolism have been identified as causing the serum triglyceride levels to see characteristic retinal vasculature abnormalities.
What does lipemic specimen mean?
Lipemic Specimen. A specimen that consists of or contains excessive amounts of fat and fatty substances. (NCI Thesaurus)
What does it mean if your blood is lipemic?
When blood is lipemic the serum is cloudy. If it is highly lipemic it will actually form a lump of fat that has to be removed and the specimen respun. It can be a disease marker or the patient ate very fatty food. Coming in after a large meal of fast food will make your blood cloudy.
What does it mean to slightly lipemic?
Slightly lipemic means that the blood is slightly high in fats. I hope my answer has helped you. Please do not rate my answer if your question is not yet fully answered.You can simply ask further by using REPLY button and I will get back to you.
What causes lipemic serum?
Table 1 summarizes the likely factors contributing to markedly elevated lipemic indices (>500). 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).
