Common Tests or Labs to Diagnose Depression
T4 = 4.612 ug/dl
T3 = 80180 ng/dl

TBG = 1220 ug/dl
CBC Complete Blood Count
Men: 1318 gm/dL
Women: 1217 gm/dL
WBC = 430010,800 cmm

Scan uses many x-ray view
Normal would show no masses, no constriction of cerebral blood flow, no obstruction of sinuses or fluid sacs.
A normal EKG is a pattern with a P wave followed by a QRS wave, with an interval rest period whereupon the pattern recurs.
P wave rate = 60100 bpm
P height < 2.5 mm in lead II
P width < .11 in lead II
PR interval= .12.20 s
QRS complex < .12 s
Normal ST segment= no elevation or depression
8 Hz most wave frequencies when awake. Some waves are recognized by shape, scalp location and distribution as well as symmetry. There are certain patterns considered normal for both awake and asleep.
Epileptics and various nerve disorders demonstrate an abnormal pattern or wave frequency of 7 or less.
