[Guest guest]

My son did 2 salivary tests on the same day, same times:

noon, .160 (<.01-.33)

evening, <.01 (.01-.20)

evening, 1.3 (1.8-12.1)

night, 1.5 (.9-9.2)

DHEA 86.5 (137-336)

My son is 15 and a half.

Does he need hc, or isocort or dhea?

his tsh is 2.23

t4 8.1 (4.5-12.0)

t3 180 (83-215) (did not test free t3)
