RDW-SD is calculated as the width (in fL) of the RBC size distribution histogram at the 20% height level. This parameter is, therefore, not influenced by the average RBC size (mean corpuscular volume, MCV). [7] RDW-CV (expressed in %) is calculated with the following formula: RDW-CV = (1 standard deviation of RBC volume ÷ MCV) × 100%. [8]
The normal hematocrit level for a woman is 36% to 48% (for men, 41% to 50%). The normal level of hemoglobin (an oxygen-transport protein found in red blood cells) for women is 12.0 to 15.5 g/dL (for men, 13.5 to 17.5 g/dL).
The CEA blood test is not reliable for diagnosing cancer or as a screening test for early detection of cancer. [8] Most types of cancer do not result in a high CEA level. [9] Serum from individuals with colorectal carcinoma often has higher levels of CEA than healthy individuals (above approximately 2.5ng/mL). [10]
Since calprotectin comprises as much as 60% of the soluble protein content of the cytosol of neutrophils, it can serve as a marker for the level of intestinal inflammation. [9] Measurement of faecal calprotectin has been shown to be strongly correlated with 111- indium -labelled leucocytes – considered the gold standard measurement of ...

Two changes in levels of tests were made from the previous four-level format: firstly, a new level was inserted between the old level 3 and level 2, and secondly, the content of the top level exam (old level 1) was changed to test slightly more advanced skills, though the passing level was not changed, [65] possibly through equating of test ...
