    Default Blood testing in the Morning vs the Night.
    So my doctor just called and wants me to re-do all of my blood work. Reason is I had blood drawn at 6:40PM. The test came back as low.

    Is there a major difference between testing in the AM and the PM?

    The doctor kept saying that my scores were in range for having the blood drawn in the PM. So I asked the obvious questions, "How much does your test drop an hour" "What is the range for PM testing" "Why does it change" I didn't get any real answers..

    Does it make that big of a difference? I am not sure what I am even looking at here.... Will those test come back "Normal" at 8:00 AM?


    TESTOSTERONE, TOTAL LC,MS,MS 212 Reference range: 250 to 1100
    Free Testosterone 37.0 Reference range: 46.0 to 224.0
    Testosterone, Bioavailable 74.4 Reference range: 110.0 to 575.0

    Your T levels are generally highest in the morning. You should get your blood drawn first thing in the morning.

    Regardless of what time you did the first test, it is standard protocol to get a second lab test done when the first one comes in low to confirm the result. Make sure you also check your LH, FSH, Prolactin, Vitamin D, Thyroid panel. Maybe a few others I am forgetting right now.

    I did have the rest of that done - it all tested positive - about 5 pages of results, including a sleep study
    I guess my question, is "Oh you are a 800 in the morning but 212 by the afternoon" common? I feel like there would have to be something else very wrong there.

    your T is probably low, sure. but you still need to get it redrawn in the morning - you need a 'correct' baseline drawn at the generally accepted time - the morning. plus, a 2nd draw never hurts.

    True. Very unlikely you are going to be 800 in the morning and 212 in the afternoon. It should be a little higher though. But I wouldn't get too worked up about having to get it retested since it is normal to confirm the first low result. Let us know where it comes in.

    Just to maybe clarify - I am terrified of going on any treatment. I hate needles, I don't think the creams seem too healthy. I would rather have a high number. But I feel like shit every day, it sucks. And I am at the point where I need to change.

    I think my doctor is an absolute idiot.

    I read (I think it was in Vergas book) that the older you are the more the difference between T in the AM and PM narrows... for someone my age (49) the difference is pretty small.

    FWIW I hated needles all my life too... almost scary how easy it was to get over that. That said, don't jump into anything - research and take your time.

    He probably is when it comes to male hormone replacement. You might see a rise of 50-100 points, which might give him a way out of treating you for low testosterone. A GOOD doctor will go by how you feel, not by some number. Most are scared of needles, but trust me - when you see how much better you feel having proper levels of hormones in your body, you look forward to those injects! Feeling better or staying off the hormones, the choice is yours friend.
