Interpretting Test Results

Posted , 3 users are following.

Hello all,

I had a 24 hour urine test that showed elevated cortisol levels. I then had a low dose 24 hour dexamethasone test. My results were as follows:

741 nmol/l

26.86 ug/dl

24 Hrs later:

57 nmol/l

2.07 ug/dl

I've read the threshold for normal results is 1.8 ug/dl...but I am sooo close? What do you all think?

    Hi Suvoth, Can you please provide extra information.

    Did you do a 24 hr urine which showed the high reading of 741nmol/l, then did you take a low dose dexamethazone at 11pm followed by an 8am blood test with results of 57nmol/l ?

    Or did you do another 24 hr urine sample taking dexamethazone ev ery 6 hrs?

    Hi Deb3313,

    I had a 24 hr urine test done a month or so again and my Endo called to let me know the results were high and then schedule the Low Dexematheson test. I didn't ask what my urine test results were at the time (silly me) but I called today to find out the results of the low dose dexa test. I haven't spoken to my endo about the results yet, just got the info from the secretary.

      Sorry, I meant to say my base reading was 741 nmol/l and the following morning was the 57 nmol/l for the low dexa test.

      Ok so if the 741nmol was before dexa and you took the one dose of dexa at 11pm and then an 8am bleed with a result of 57nmol/l its so close to a suppression result, I am sure your Endo will say you suppressed.

      You will need to have further testing before they will diagnose. Usually the Endos will do several rounds of the same test each month for a few months, just to be sure. You should also be having ACTH levels checked.
