Quest VS LabCorp: Understanding Different Ranges
I have done a blood work this time with Quest and comparing my previous lab done with LabCorp, I see that Quest has ranges a bit different, for example it could allow more or less of a certain unit for a determinate test, so if I'm understating well, comparing a same number for a determinate test, for Labcorp may be in range but for Quest may be out of range correct? or we would need to consider the different range to determine if result is in range or not? does it make sense?
Doc sent me for Estradiol sensitive but I believe this is not, cause on previus BW I was on 0.07AI twice a week, for the Quest one I was on 0.07 3 x week so I should see a decrease.
What do you guys think of Ferritin? after the Labcorp BW I donated just once, at the end of January, could really be this low??
I started caber 0.125 2 x week so prolactin went low
I definitely lost some libido and sex interest, I was attributing that to low E2, but unfortunately I do not have a sensitive test for estradiol so who knows what my levels is

Did you attach specific lab results, or is your question a general one in regard to differences with the ranges established by LabCorp and Quest?I am not a physician.

Were the two pairs of tests from both companies taken the same day?
Yes, every lab uses their own ranges generated by their own data. There is no federal or guideline requirement for all labs to use the same ranges even if using the same assay method.
Also, even if we are taking TRT + HCG + anastrozole at a stable dose each for weeks, we will have a fluctuation of plus or minus 10-20% due to hydration status, and liver and kidney metabolism changes that naturally occur.

Ferritin should drop about 30, if I remember correctly, after donating a pint, my Ferritin end of January was 80, I donated then so it should have dropped to 50, at the end of January....after two months with no donations dropped to 28? I'm thinking something is off, whether Quest or me
