What lab 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 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.

Difference with ultracentrifuged serum, calculated as bias. 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.
How do you remove lipemia?
High-speed centrifugation (10,000×g for 15 minutes) can be used instead of ultracentrifugation to remove lipemia in serum/plasma samples.
