Test Category
Specimen Requirements

​Fasting

Required

Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)
​No​Plasma or Serum Lithium-Heparin ​Plasma Separator Tube (PST)

Serum Separator Tube (SST)

​Red Top Tube (RTT)

​1.0 mL ​0.3 mL
Collection Processing Instructions
Separate plasma or serum from the blood within 60 minutes of venipuncture. Specimen must be free of particulate matter including fibrin which can interfere with the assay.
 
High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay. It is recommended that patients refrain from consuming any multivitamin or supplement containing biotin for at least 72 hours prior to collection of a blood sample.
Specimen Stability Information
Specimen Type Temperature Time
​Serum or Plasma ​ ​Room Temperature ​8 hours
​Refrigerate <72 hours​
​Frozen (-20 C) ​1 month
​Frozen (-70 C) ​>1 month

Preferably specimens should be frozen.

Avoid freeze and thaw samples.  One freeze and thaw is acceptable.​ ​ ​

Interference

High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay.

Heterophile Antibodies and Rheumatoid factor can react with reagent immunoglobulins.  Human anti-mouse antibodies may cause falsely low or high results.  Troponin autoantibodies may interfere.
