The above link is for Direct Labs. I have been buying blood tests from them for about a year. They use Quest Labs which is a a very reputable diagnostic laboratory. I got the test every month while I was trying to avoid heavy pharmaceutical treatment. The email results directly to me within 24 hours. PSA is one of the tests of the month for June. $29 instead of the normal $44.
It helped me respond quickly when PSA rose gently as 2019 started after 6 months hovering around 1. After Auximen PET my PSA took off like a rocket ship as I started to investigate treatments. 2.4 in Feb, 3 in March, 5.8 in mid-April as I took PET scan, 47.3 on May 6 at MSKCC.
Insurance was approving 3 months. I wanted every month and It is really easy and convenient and I think remarkably cheap.
It is not available in a few states. Notably, NY and NJ. Pa is where I live and it is available here.
I believe Direct Labs saved me time responding.
