700 C 1 - Camco® Positive Control Solution


This box contains one bottle of the Positive Control Solution. The Fecal Occult Blood Camco Positive Control provides hemoglobin/heme moieties in a control matrix that will react positively with the Guaiac and peroxide Developer, giving the same blue color. Thus, the Control demonstrates that the test system is chemically functional. Now sold separately, this quality control solution is 5mg /dL bovine hemoglobin in an aqueous buffered solution with preservative. 

Quality Control:

  1. Follow the manufacturer’s instructions for controlling this assay.

  2. The patient specimen should always be developed prior to performance of the CONTROL TEST (Unless the control test is being done alone).

  3. Gently mix the Positive Control by several inversions; place one small drop on the “Control” area on the back of the slide.

  4. After the drop has been absorbed, add two drops of Developer to the “Control” area.

  5. A blue color should form within thirty seconds. If no color forms, the test may be invalid and the patient test results should not be reported.

  6. If the Control tests as negative, retest all patients who tested negative.

  7. The blue color from the Positive Control should not be regarded as the intensity required from a positive patient test for occult blood in the stool.

  8. Read results up to thirty seconds. Disregard any colors that form after thirty seconds.

Negative Note: If a negative control is desired, one or two drops of water may be used to give a negative test reaction
