Overview: Follicle-Stimulating Hormone TestIntroduction: The Follicle-Stimulating Hormone Test measures follicle-stimulating hormone to assess fertility or hormonal disorders, causing infertility or irregular periods. Aligned with 2023 ASRM guidelines, it uses an immunoassay for high sensitivity, aiding in endocrine screening. This test is critical for guiding diagnosis, treatment, and improving outcomes in endocrinology for patients with fertility issues.
Other Names: FSH Assay, Gonadotropin Test.
FDA Status: Laboratory-developed test (LDT), meeting endocrinology standards for diagnostic accuracy.
Historical Milestone: FSH testing began in the 1970s with fertility research. Immunoassays emerged in the 1980s, and by the 2000s, high-sensitivity assays improved accuracy.
Purpose: Diagnoses fertility or hormonal disorders, guides treatment, and monitors FSH levels in patients with infertility or irregular periods.
Test Parameters: 1. Follicle Stimulating Hormone
Pretest Condition: Fasting for 10-12 hours required to stabilize hormone levels. Collect serum or plasma in the morning. Report symptoms like infertility or irregular periods, and list medications.
Specimen: 2-5 mL serum (SST) or 2-4 mL plasma (EDTA). Centrifuge within 1 hour. Transport in a biohazard bag within 8 hours.
Sample Stability at Room Temperature: 8 hours
Sample Stability at Refrigeration: 7 days
Sample Stability at Frozen: 6 months
Medical History: Document infertility, irregular periods, or history of hormonal disorders. Include current medications, especially hormonal therapies.
Consent: Written consent required, detailing the tests purpose, diagnostic implications, and potential need for fertility treatment.
Procedural Considerations: Uses an immunoassay to measure FSH levels. Results are available in 1-2 days, enabling rapid clinical decisions.
Factors Affecting Result Accuracy: Non-fasting, hemolysis, or medications can affect results. Menstrual cycle phase may alter levels.
Clinical Significance: Abnormal FSH levels suggest hormonal or fertility disorders, prompting treatment. Normal levels may require further testing.
Specialist Consultation: Consult an endocrinologist or reproductive specialist for result interpretation.
Additional Supporting Tests: LH levels, AMH, or pelvic ultrasound to confirm fertility issues.
Test Limitations: Results vary by menstrual cycle phase. Clinical correlation is required.
