Lipemia can affect chemistry results by:

Lipemia introduces turbidity in plasma from excess lipids, especially chylomicrons after a fatty meal. In chemistry testing, many assays rely on photometric measurements where light passes through the sample to detect color changes or absorbance. The milky, lipid-rich plasma scatters light, distorting the light path and altering absorbance readings. This interference can lead to results that are falsely high or low, depending on the specific assay and method used. Labs may flag lipemic samples and use lipid-removal steps or alternative methods to mitigate the bias. This isn’t about white blood cells or lipid deficiency, and lipemia doesn’t simply enhance assay sensitivity.
