Research published in the book Human Chorionic Gonadotropin (hCG) found that CVS One Step could only detect hCG concentration of 100 mIU/mL. The ‘digital revolution’ is important as 1 in 4 women can misread a line test 7. Postmenopausal females: 0 – 8 mIU/mL, Medical Sources Research carried out by the Department of Obstetrics and Gynecology at the University of New Mexico revealed that e.p.t. Results: Universal claims for OTC-PTs of more than 99% laboratory accuracy and use as early as the first day of missed period, while cleared for use by the U.S. Food and Drug Administration, are ambiguous and inappropriate for many products, according to these data. Setting: Medical school laboratory. By the 10th day, hCG levels reach 12 mIU/mL and by day 11, 25 mIU/mL. 4 weeks LMP: 5 – 426 mIU/mL Epub 2005 Jun 20. When hCG level is below 1000 mIU/mL, only one coloured band appears in the control window but no coloured band appears in the test window. Setting: Many women mistake this for a positive result, only to realize later that it was not a positive result. However, it is important to recognize that the 'beta-subunit' antibody reacts with both intact HCG, which is the major component in pregnancy serum, and with fragments of the beta-subunit (beta-core), which are the major form in urine. Interventions: Contrary to popular belief, however, this is not something you can detect right away. None. tests aren’t as sensitive and accurate as claimed. Despite the fact that hCG levels typically double every 48 to 72 hours, most women begin with a level of less than 5 mIU, which is a level that does not indicate pregnancy.
