I have a 34 month old little boy. We have had blood test run and three times his numbers were a little low and testosterone is a one. We have seen genetics and he seems to think ichthyosis vs ectodermal displaysia. He does not sweat darkening scales around face elbows, etc We have seen Endo. and he ran antibody test on adrenal gland and he said numbers are in normal range and wants to retest in 1-2 years. We saw allergist today and he is running humoral immunity test and is getting the endo. to run a ACTH stimulation test. Im confused. I have been told testosterone levels arent important at this age by one doc and been told diff by another. Are they? Going to Gainsville to UF to see Dermatologist. Any suggestions to help get diagnosed? Will not have blood test results back for derm appt.
