A Person has been complaining of feeling tired, having no energy and seems to be putting on weight steadily. Doctor orders lab work for TSH, WBC, Hemoglobin, and lytes. He also orders an in and out catheter for a urine sample.
I understand that Dr. Order TSH lab test as patient is putting on wt. and it could be because of increased secretion of TSH, hemoglobin test for tiredness but why he ordered WBC, lytes and urine test
