Fluorescence Quantitation

Reference ranges:

Normal:
≤ 2.0 mg total hemoglobin/g feces

Marginal:
2.1 - 4.0 mg total hemoglobin/g feces

2.1 - 4.0 mg Hb/g is considered marginally elevated, but not clinically significant, if red meat, warfarin, or aspirin was ingested 72 hrs prior to collection.

Elevated:

>4.0 mg total hemoglobin/g feces

Cautions:

Heme from ingested red meat will increase HemoQuant test values. Patients should be advised to avoid eating red meat for 3 days before collecting specimens. Fish and poultry may be substituted.

The elevated porphyrins of lead intoxication, erythrocytic protoporphyria and variegate porphyria may raise HemoQuant values in the absence of gut bleeding.

Recent studies have indicated that cancerous lesions in their early stages often do not bleed or bleed only intermittently.
