4.0 ml Gold-top serum separator
2 ml serum, minimum 0.5 ml
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.
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.
Room temperature: 8 hours; Refrigerated: 24 hours Gold-top serum separator tube; Refrigerated: 72 hours if serum is poured off into an Aliquot tube.
If not centrifuged within 2 hours of collection.
Males: 0.28 – 1.22 ng/ml
Follicular Phase = 0.15 – 1.40 ng/ml
Luteal Phase = 3.34 – 25.56 ng/ml
Mid Luteal Phase = 4.44 – 28.03 ng/ml
Post Menopausal female = 0 - 0.73 ng/ml
Daily, Monday - Sunday
