Individual tests

The fecal occult blood test (FOBT) checks stool samples for hidden (occult) blood. Occult blood in the stool may indicate colon cancer or polyps in the colon or rectum — though not all cancers or polyps bleed. If blood is detected through a fecal occult blood test, additional tests such as a colonoscopy may help determine the source of the bleeding. The fecal occult blood test can only detect the presence or absence of blood — it can't determine what's causing the bleeding.
Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. There are several types of hemoglobin. Hemoglobin electrophoresis is a test that measures the different types and identifies abnormalities.

Serum protein electrophoresis (SPE) is an analytical technique that separates serum protein into six fractions: albumin, alpha-1, alpha-2, beta-1, beta-2, and gamma. Interpreting elevation, decrease, or visual change in different fractions can diagnose various disease states and protein abnormalities.
