Check your facts. The Battelle paper used BNP to detect TB. UTHSC used BNF to detect GBS. If you read the scientific paper carefully, the researchers said that along the way, they discovered that results could be gotten faster (with BNF) by making changes. I believe they began this faster method as soon as they finished with the original BNF study.
Dr. Faro says based on his study, the BNF method used is good for women before labor. The new quicker version, if proven successful, will also capture women during pregnancy.
