Point-of-Care and Over-the-Counter Qualitative Human Chorionic Gonadotropin (hCG) Devices Remain Susceptible to False-Negative Results Caused by Excess hCG β Core Fragment
For many taking a home pregnancy test can be upsetting, particularly if there is not complete confidence in the result. The November 2013 print issue of Clinical Chemistry published a paper from a group led by Dr. Ann Gronowski that reported false-negative results in point-of-care and over-the-counter qualitative hCG devices.
