Performance Characteristics Detection Limit:  1 mIU/mL  ; Linear Range:  1.0~200 mIU/mL; Linear correlation coefficient R ≥ 0.990; Precision: within batch C.V. is ≤ 15%; between batches C.V. is ≤ 20%; Accuracy: the relative deviation of the measurement results shall not exceed ± 15% when the accuracy calibrator prepared by FSH national standard or standardized accuracy calibrator are tested. Cross-Reactivity:The following substances do not interfere with the TSH test results at the indicated concentrations: LH at 200 mIU/mL, TSH at  200 mIU/L and HCG at100000 mIU/L 1. Store the detector buffer at 2～30℃. The buffer is stable up to 18 months. 2. Store Aehealth Ferritin Rapid Quantitative test cassette at 2～30℃, shelf life is up to 18 months. 3. Test cassette should be used within 1 hour after opening the pack. Follicle-Stimulating Hormone is a kind of glycoprotein hormone secreted by basophil and the molecular mass of 30kD.FSH is controlled by hypothalamic gonadotropin releasing hormone, and its function is to promote the development of follicle. The male promotes the formation and spermatogenesis of the vasculum. According to the middle period of the menstrual cycle, FSH and LH reached the peak value at the same time, and FSH increased to predict ovulation. Detection of follicle-stimulating hormone concentration for amenorrhoea, primary low sex gland function, secondary low sex gland function, precocious puberty, polycystic ovary syndrome, climacteric syndrome, the diagnosis of pituitary adenomas has important clinical significance.
