    Question ACTH Stim Test Results - Secondary AI?

    Hi everyone.

    Here is the info. (normal range in brackets)
    1mcg of cosyntropin injected.

    Stimulation Test
    9:44 am (PRE) 3.0 (0.0 – 10.1) pmol/l
    10:33 am (POST) 2.4 (0.0 – 10.1) pmol/l

    9:44 am (PRE) 363 (170-720 in the am) nmol/l
    10:33 am (POST) 257 (170-720 in the am) nmol/l

    Separate (not done by endocrinologist) ---- Thyroid
    Dec. 2010 TSH = 0.83 (0.30-5.6) MU/L
    Feb. 2012 TSH = 0.41 (0.30-5.6) MU/L
    Jun. 2012 TSH = 0.40 (0.30-5.6) MU/L
    Sept. 2012 TSH = 0.31 (0.30-5.6) MU/L
    T4 Free = 10.7 (7.2-21.0) pmol/l
    Free T3 = 4.5 (2.9-6.0) pmol/l

    Do you think that these results mean anything? I have quadruple checked the bloodwork and it is not a mistake that my cortisol actually dropped from PRE to POST ACTH injection. Do you think this could be a lab mistake? Even if the tubes were switched - it did not exactly double. I think it is a bit weird. I never had a followup appt, I had to switch family dr's soon after the test so really had no followup with these issues with anyone, and I did not get the records until recently.

    Thank you in advance for any insight!
