WebAs for women, the reference range is menstrual cycle phase-specific. The reference range for follicle-stimulating hormone (FSH) is as follows (3rd generation immunochemiluminescence assay): Females. · Age 0-7 years: <6.7 mIU/mL. · Age 8 years to adult: · Follicular phase: 3.1-7.9 mIU/mL. WebA serum TSH below 0.1 mIU/L may be present in 5% of women by the 11th week of pregnancy. The TSH subsequently normalises as beta-HCG falls in the second and third trimesters. In view of these physiological changes, consult gestation-specific TSH concentration ranges when interpreting thyroid function tests.
