Plasma, Human, LH Free, Low FSH

All plasma is obtained from FDA-licensed facilities in the United States.\n\nNormal FSH test results vary according to age and sexual maturity. The phase of a woman's menstrual cycle or use of birth-control pills also affects test results. For an adult male, normal results range from about 4-25 units of FSH in every liter of blood (U/L) or about 5-20 micro-international units in every milliliter. For a premenopausal woman, normal values range from 4-30 U/L or 5-20 micro-international units per milliliter. In a pregnant woman, FSH levels are too low to measure. After menopause, normal values range from 40-250 U/L or 50-100 micro-international units per milliliter.\n\nFSH levels fluctuate during premenopause. If no other symptoms are present, an elevated FSH level should not be interpreted as proof that menopause has begun. The FSH test is the simplest method we know of in 1998 to test the ability of the eggs to talk back to the brain. If the system is functioning the way it should, then the FSH level early in the cycle should be on the lower end of the scale. How low? That depends on the laboratory doing the testing. Each lab, by nature of the way the test is done there, will report a different level for a given test. One of the great confusions regarding FSH testing is that a similar level means very different things at different places. Also, some clinics characterize their tests very carefully; others less so. FSH is reported in "units" and results from 2 units to 7 are probably normal in just about any lab. Levels above 25 are probably abnormal. The area between 9-24 may represent normal or abnormal levels, depending on how the test is performed.\n\nQuality Control:\nSource plasma is tested and certified negative for HIV 1, HIV 2, HIV-Ag, HBsAg, HCV, RPR and ALT.\n\nRecovered plasma is tested and certified negative for HIV 1, HIV 2, HIV-Ag, HBsAg, HCV, HBc, HTLV-1,RPR and ALT.\n\nCustom Manufacturing:\nUser-defined Analyte Values, Total Protein and Filtration, Source, Sex and Age, Preservatives, Lipid Levels, Packaging, Vialing, Multi-level Calibrators and Controls.
