This document provides reference ranges for numerous hematological and biochemical parameters. For red blood cell count, hemoglobin, hematocrit, and other red blood cell indices, it lists the normal male and female values and describes conditions that could cause high or low results, such as anemia or polycythemia. White blood cell counts and differentials are also outlined, along with normal ranges and potential issues indicated by abnormal levels. Urinalysis parameters, thyroid function tests, and liver function tests are similarly summarized.

(microcytic);
caused by iron
deficiency anemia.
Mean
corpuscular
hemoglobin
(MCH)

macrocytic RBC are
large so tend to have
a higher MCH

32-36% Indicates
hemogoglobin is
more concentrated
inside the red cells,
such as autoimmune
hemolytic anemia, in

May be low when
MCV is low;
decreased MCHC
values
(hypochromia) are
seen in conditions
such as iron

Mean platelet
volume(MPV)
7.4-10.4fl High number
indicates bone
marrow producing

platelets rapidly into
circulation.

indicate
production of
platelets by the
bone marrow
