The widely used [21] rule calculating normal maximum ESR values in adults (98% confidence limit) is given by a formula devised in 1983 from a study of ≈1000 individuals over the age of 20: [22] The normal values of ESR in men is age (in years) divided by 2; for women, the normal value is age (in years) plus 10, divided by 2.

Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5–15.4%. [2] [1] If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia. It is mainly used to differentiate an anemia of mixed ...
A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). [2] It is determined by collecting data from vast numbers of laboratory tests.
Under the heading "Normal Values", in the subsection "Adults", there is a serious contradiction between the formula for ESR and the table beneath it. According to the table, for a 90-year old man, the normal upper limit for ESR value is 19. But according to the formula, the normal upper limit is (90 + 0)/2 = 45.
The white blood cell differential is a common blood test that is often ordered alongside a complete blood count.The test may be performed as part of a routine medical examination; to investigate certain symptoms, particularly those suggestive of infection or hematological disorders; [5] [6] or to monitor existing conditions, such as blood disorders and inflammatory diseases.
A reticulocyte count that is high, normal or low will aid with the classification process. A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells. Acute blood loss would result in a high reticulocyte count ...
