LabCorp recommends your Hemoglobin levels be between 13.0 and 17.7 g/dL. What if you could test your Hemoglobin levels from the comfort of your own home to know when it’s time to give blood while on TRT? I found two meters and I test them for ease of use and accuracy in this video. Always check your Hemoglobin and when it gets high, donate blood!
