​FSH, Pituitary Gonadotropins​
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
No​ Serum​ Serum Separator Tube (SST) ​Red Top Tube (RTT)​ 0.5 mL​ 0.4 mL​ 0.3 mL​
Collection Processing Instructions

Specimen Stability Information
Specimen Type Temperature Time
Serum​ Ambient​ 8 hours​
Refrigerated​ 7 days​
Frozen​ >7 days​
Rejection Criteria
​Moderate hemolysis
Interference
Human Anti-Murine Antibodies (HAMA) may develop leading to test interference in patients receiving murine-based agents for chemotherapy or tumor-imaging studies.​​
 
For testing performed at The Diagnostic & Treatment Center lab (Weston Center): 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.
