This description aims to provide patients with some useful information on the tests which may be included as part of their health screening. The tests are explained briefly. Because reference ranges are typically defined as the range of values of the median 95% of the healthy population, it is unlikely that a given specimen, even from a healthy individual, will show “normal” values for all tests. All results should be correlated with patient’s history and clinical findings. Therefore, your physician is the best person to interpret your laboratory results. Always consult your physician.
Stool FEME test screens for the presence of eggs (ova) of parasitic worms. For example, hookworms and roundworms, cysts of protozoa such as giardia lamblia and amoeba and also the presence of red blood cells and white blood cells in the stool.
Screening of the stool for OB is useful for the detection of suspected bleeding in the gastrointestinal tract (GIT). It is necessary to abstain from certain food such as red meat, cauliflower and broccoli three days before the test to prevent a false positive result. The presence of haemorrhoids or piles may also give a false positive result.
