To convert mg/dL to mmol/L (SI units) multiply by 0.0259.

The HDL result may be falsely elevated when triglyceride concentrations exceed 1000 mg/dL.  The HDL result may be falsely low when conjugated bilirubin concentrations exceed 33 mg/dL.

Monoclonal proteins have been reported to cause falsely low HDL results in a variety of direct HDL methods.

According to the Abbott Architect package insert, using three homogenous HDL assays, Camps, et al. have reported artificially low HDL results in patients with liver cirrhosis. Published studies are not available that define the severity of liver disease necessary to affect lipoprotein and HDL metabolism, or establish other possible patterns of interference with HDL results. When an HDL result is diagnostically critical with concomitant clinically relevant liver disease, use a recognized precipitation or ultracentrifugation HDL‑reference method for confirmation. Artificially decreased or increased HDL values in the presence of dyslipidemias have been reported. N-Acetyl-L-Cysteine at elevated concentrations may lead to falsely low results.
