Clinical Biochemistry
Sample and container requirements
Serum EDTA Plasma Lithium Heparin Plasma (paediatrics only)
Minimum volume required
Special requirements
None
Patient preparation
Samples from patients receiving high biotin doses (i.e. >5 mg/day) should be taken at least 8 hours post-dose. Please inform the laboratory if the patient has been treated with monoclonal mouse antibodies or may have received them for diagnostic purposes.
Sample viability
Turnaround time
This assay is run throughout the day and night. The in-lab turnaround time is normally less than 24 hours.
Reference range
Females: Follicular phase: 3.03 – 8.08 IU/L Luteal phase: 1.38 – 5.47 IU/L At ovulation: 2.55 – 16.69 IU/L Post – menopausal: 26.72 – 133.41 IU/L Males: 0.95 – 11.95 IU/L (Source: Abbott Diagnostics)
Clinical guidance
Follicle Stimulating Hormone (FSH), like Luteinising Hormone (LH), belongs to the gonadotropin family. They synergistically regulate and stimulate the growth and function of the ovaries and testes.
