Which other analyte is affected by high triglyceride levels besides chloride?

High triglycerides make the serum lipemic, which distorts tests that rely on optical readings or on lipid-separation steps. HDL cholesterol is often measured after precipitating out the non‑HDL lipoproteins to isolate HDL. The lipemic matrix disrupts that separation and can alter the colorimetric signal used to quantify HDL, leading to unreliable HDL results when triglycerides are very high. That makes HDL the analyte affected beyond chloride in this context. Potassium measurements are typically more robust with direct measurement methods and are less susceptible to lipemic interference, which is why they’re not the best match here. The chloride result can be variably affected by some indirect methods, but the lipemic impact is most consistently observed with HDL in these assays.
