Which analyte shows a false increase with high triglyceride levels?

Lipemia from high triglycerides scatters light and can alter the reading of some assays. Chloride measurements, often done with ion-selective electrodes or certain colorimetric methods, can be artificially elevated in lipemic samples because the lipid turbidity changes the sample matrix and interferes with the measurement. This creates a false increase that does not reflect the true chloride concentration. Other analytes like HDL or ALT are either less affected by this specific interference or measured with methods that tolerate lipemia better, so they don’t show the same false rise in the presence of high triglycerides. Ammonia measurements can be affected by turbidity as well, but the question highlights chloride as the analyte prone to a false increase under lipemic conditions.
