Had 24hr sodium to eval hypovolemia, can't find info on how the results tie to volume status ?

Since you already: have the diagnosis of dysautonomia your health care professional is trying to determine how bad your volume regulation might be. For adults, normal urine sodium values are generally 20 mEq/L in a random urine sample and 40 to 220 mEq/L per day (mEq/L/day). High levels may indicate adrenal gland insufficiency. Low levels mean hypovolemia (dehydration) or adrenal over activity. Hope that helps.
