collection instructions

  • Collect blood in a serum separator tube (SST) or a lithium heparin tube.

  • Allow the blood to clot at room temperature for 30 minutes if using an SST.

  • Centrifuge and separate serum or plasma from cells within 2 hours of collection.

  • Transport the specimen at 2-8°C if not tested within 2 hours.

collection instructions

  • Hemolysis: Red blood cell destruction can falsely increase glucose levels.

  • Improper Labeling: Specimen must be labeled with at least two patient identifiers.

  • Insufficient Quantity: Volume less than 1 mL may not be sufficient for accurate testing.

  • Lipemia: Excessive fat in the blood can interfere with certain test results.

clinical significance

The Direct HDL Cholesterol (DHDL) test measures the level of high-density lipoprotein (HDL) cholesterol in the blood. HDL is often referred to as "good" cholesterol because it helps remove other forms of cholesterol from the bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of cardiovascular disease. This test is used to assess cardiovascular risk and monitor the effectiveness of lipid-lowering treatments.
