Coronavirus testing has been a hot-button issue since the beginning of the pandemic. First, there weren't enough coronavirus tests to go around. Now, a new issue has emerged—just how accurate the tests people are getting actually are. According to a July 17 study published in the International Journal of Geriatrics and Rehabilitation, 50 percent of nucleic acid coronavirus tests distributed by the Centers for Disease Control and Prevention (CDC) provided inaccurate results.
The study's lead author, Sin Hang Lee, MD, director of Milford Molecular Diagnostics Laboratory, found that the testing kits gave a 30 percent false-positive rate and a 20 percent false-negative rate.
To determine these false-positive and false-negative rates, the Connecticut State Department of Public Health Microbiology Laboratory provided Lee 20 tests, which were then re-tested using his own methodology, which examines samples on a cellular level, rather than just testing fluid with no cellular matter from potentially infected oral and nasal secretions.
