Clinical Notes

The primary use of a creatinine test is to better understand how well the kidneys are working. A measurement of creatinine can be employed for screening, diagnosis, and/or monitoring of kidney problems.DHEAS is produced almost exclusively by the adrenal glands, with smaller amounts being produced by a woman’s ovaries and a man’s testicles. A DHEAS test is useful in determining whether the adrenal glands are working properly. Adrenal tumors (cancerous and non-cancerous) and enlargement of an adrenal gland (hyperplasia) can lead to an increased level of DHEAS. Rarely, an ovarian tumor may produce DHEAS.
