GFOBT

In the land of feces, where secrets lie, There's blood that's hidden from the eye. Not visible, not easy to see, A mystery in the stool, it may be. A test we have, called FOBT, To check for blood that's occult, you see. No melena or hematochezia in sight, Just hidden blood, lurking in the night. The American College of Gastroenterology knows, That gFOBT is not the way to go. FIT is the test they recommend, To find the blood, and make amends. Newer tests look for globin and DNA, Or other blood factors that come into play. Transferrin and heme, they search for too, To detect the hidden blood, through and through. So remember, my friends, when it's time to check, For hidden blood that may be a wreck, The FOBT may be a thing of the past, But FIT will find the blood, and it will last.
