Test ID: FHDLS    
HDL Cholesterol Subclasses

Specimen Type Describes the specimen type needed for testing

Serum

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Draw blood in a plain red-top tube(s), serum gel tube(s) is acceptable. Spin down and send 3 mL of serum refrigerated in a plastic vial.

Required: Fasting for at least 12 hours. If a cholesterol measurement is to be performed along with other lipid tests, the patient should fast 9-12 hours prior to collection.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
