Activated Protein C-Resistance

What this laboratory test evaluates

DetailsActivated Protein C-Resistance – Activated protein C (APC) resistance is the most frequent hereditary defect associated with deep vein thrombosis. Over 95% of the APC resistance phenotype is due to the Factor V Leiden mutation. The APC-Resistance assay is a plasma-based functional test for the determination of APC resistance caused by the factor V Leiden mutation.

What type of sample is required for this test?2 mL frozen platelet-poor citrated plasma collected in a 3.2% sodium citrate (light-blue-top) tube

How Sunridge uses laboratory information

Sunridge considers the medical question, symptoms, history, medications, prior results, and whether the finding could change care before recommending testing. A laboratory result is not interpreted in isolation and does not establish a diagnosis by itself.
