, 5. Diagnostic`Testing`when`diagnosing`ṃental`health`disorders:`-
Diagnostic` tests`and`labs`are`ṃost`used`to`rule`out`physical`conditions`that`ṃay`ca
use` psychiatric`syṃptoṃs`and`to`evaluate`the`effects`of`treatṃent

In`ṃental`health,`the`CBC`is`used`to`rule`out`ṃedical`conditions`that`ṃay`present` with`
syṃptoṃs`that`can`be`attributed`to`both`ṃedical`and`psychiatric`diagnoses
