Jim..The lol and 49er made a good point..That study proves DR-70 alone is not a good bio marker for lung cancer.. That is why William's combination..Radient and Provista Dx LC Sentinel is better than DR-70 alone..Who would want DR-70 by itself..Obviously not Uni Pharma and Provista DX and Radient/AMDL Inc...imo Wolf Pack
