    Testosterone No Good After 28 Days???

    My CNP wrote me a new script for 10ML of 200MG/ML. When I went to Sam's to pick it up, they had a 1 ML vial.

    Different Labs - Different Results?

    I'm a Defy patient and I've been using LabCorp for 3 years. My NP has ordered another PSA test through TriCore as my PSA went up. I'm considering using TriCore as my insurance will cover it. Do they use the same testing methods? Will they produce similar or different results? Thanks.

    Prostate MRI Screening

    Is Prostate MRI Screening a viable alternative to ultrasound directed biopsies? I'm considering having this done as a screening much like a colonoscopy or mammogram. My PSA tends to be high and DRE's are normal. I just want some peace of mind. The latest Prostate MRI's are non-invasive and a...
