Synonyms

Progest; P4 

Specimen Type

Serum 

Container

4.0 ml Gold-top serum separator

Collection Instructions

None

Volume

2 ml serum, minimum 0.5 ml

Additional Information

Studies suggest that storing Progesterone samples in separator tubes (SST) can affect progesterone results.  Progesterone samples collected in SST tubes should be tested within 24 hours. 
(See below for Specimen Stability up to 72 hours.) 

Heterophilic antibodies in human serum can react with reagent immunoglobulins, interfering with in vitro immunoassays.  Patients routinely exposed to animals or to animal serum products can be prone to this interference and anomalous values may be observed. 

Patient Preparation

none

Specimen Processing Instructions

Serum:  Allow to clot.  Centrifuge at 3380 rpm’s (±100) for a minimum of 10 minutes

Centrifuge within 2 hours of collection.

If not sent to lab on day of collection, remove serum into an aliquot tube and refrigerate for up 5 days.

Transport Requirements

Refrigerated

Specimen Stability

Room temperature:  8 hours;  Refrigerated: 24 hours Gold-top serum separator tube;  Refrigerated: 72 hours if serum is poured off into an Aliquot tube.                                                

Rejection Criteria

If not centrifuged within 2 hours of collection.
