Sircorp,
the company is on the verge of having a sizable slice of the Latent TB testing market written into Law via the CDC.
A large number of other countries follow the CDC guidelines.
TST suffers from false positives from BCG innoculation QFT does not.
The CDC has agreed.
Japan Europe and US migrants all BCG innoculated.
$3.00 is good value at this juncture. (IMO)
Regards,
