I wouldn't buy it. CBC - Complete Blood Count is $32 from discount labs, I think it's even cheaper if you buy from Defy.
I am in the same boat, where getting labs isn't always convenient. If you don't mind me asking, which monitor do you have?I am going to offer a different opinion than those already posted. I've been on TRT for over 13 years and have always been one that has to pay attention to Hb and HCT because it wants to creep up on me. Unlike some, my Hb and HCT have never seemed to normalize. Although I have blood work done on a very regular basis, there are times in life when I just can't get down to the lab because other commitments and travel. So, about 6 months ago my wife and I purchased one of these monitors to attempt to track those two elements between blood draws.
We wondered how accurate it would be, but figured that while it might not be as accurate as results from a lab, maybe it would provide some trending if it was consistent in how it calculated the results. If that was true, at least I would be able to see some trending. To our surprise, the monitor has been relatively accurate. We use the monitor prior to having blood work done and then compare that result to what the lab results show. Normally the monitor is only two or three tenths off the lab result. Once, it was a little higher than that; the monitor gave me a result of Hb 16.0 and HCT 47.0% and the lab results on the same day gave me a result of Hb 16.4 and HCT 48.%.
We do not use it to replace having blood work done, we simply use it as another tool to assist me in my TRT therapy and managing my protocol.
For some reason, I cannot open the discountedlabs.com website. Never have been able to. Security.There is one way to prove how far off the meters are from actual measurement.
Get your CBC done and measure your hematocrit close to the blood draw time. Spend 38 dollars to prove this.
