REFLEX TESTING	Reflex testing occurs when tests are automatically added to an original order based on an individual analyte(s) value. This process provides relevant, cost effective testing. The following are subject to reflex testing:
	CBC (Complete Blood Count with Automated Differential	Manual differential, RBC morphology, etc. added for abnormal CBC parameters
	Urinalysis	Microscopic Exam added for abnormal urine chemistries (blood, protein, leukocytes, etc.)
	Accuchek (Capillary Whole Blood Glucose	Glucose test performed in main laboratory for any accuchek <50 or >350 mg/dl.
	Bacterial Cultures	Gram stains are performed automatically on: sputums, wounds, body fluids and tissues.
	Bacterial Cultures	Identification and Susceptibility testing performed when pathogens are isolated.
	Urine collected aseptically (bladder tap, catheter) on child <13 years of age	Culture automatically added for child<12 if bladder tap or catheter specimen/
	Tissues	Special stains or tissue consults may be added based on pathologic diagnosis.
	Breast Tissue Biopsy	All breast tissue with a diagnosis of cancer are referred to the reference laboratory for estrogen and progesterone receptor analysis (ERA/PRA).
	Type and Screen	Two Unit Crossmatches for all positive screens
REFLEX TESTING CONT’D:	Cardiac Profile	If CK >20, a CKMB (Immunoassay) is reflexed.
	Acetone, Serum	Titer is reflexed on positives.
	RPR	MHA-TP to the State for all Reactives.
