I’ve finally found a lab in Canada that allows for elective, out of pocket SHBG testing, and based on many of the posts here stressing the importance of knowing ones SHBG levels, I’d like to get it done.
My question - from what I’ve read, SHBG levels fluctuate very widely based on a number of factors. It seems like even eating a Tic Tac will cause it to either skyrocket or plummet. When should I take my test for this (ie: x days after a shot, morning/noon/night., etc) and is there anything else I need to be mindful of? It’s a pricey test up here and I’d like to get it right
Thanks
Do not test SHBG within 24 hours of a workout, it will be momentary elevated. Test after one of your rest days.
SHBG and T are tied together … doctors have always told me to take in the early morning, just as you do with T labs.
Any other opinions on this? I can’t seem to find a consensus on this topic. My doctor is hesitant to prescribe an SHBG test because of how widely levels can fluctuate in response to various factors; I myself am starting to question the relevance of what amounts to a snapshot of my SHBG levels when it could go way up or way down an hour later…
It doesn’t fluctuate too much, mine hasn’t shown much fluctuation, 16-18 on multiple tests. You need to find the range where your SHBG is hovering.
Doctor is more concerned about costs for the test, yet doesn’t realize how important testing SHBG. Your doctor is operating outside of his comfort zone, find another hormone doctor.
