Hem. Glob. media en pg =
mean cell hemoglobin (MCH) (hemoglobin divided by RBC count)


C.H. Glob. Media em % =
mean cell hemoglobin concentration (MCHC) (hemoglobin divided by hematocrit)

From Harrison Principles of Internal Medicine:

Table 59.3. Normal Values For Red Cell Indices
Mean cell volume (MCV) — 90 ± 9 fL
***Mean cell hemoglobin (MCH) — 32 ± 2 pg***
***Mean cell hemoglobin concentration (MCHC) — 33 ± 3%***
Red cell distribution width (RDW) —
RDW-CV — 13 ± 1%
RDW-SD — 42 ± 5 fL

Glob. = glóbulo = corpuscle

Red blood corpuscles (Physiol.), in man, yellowish, biconcave, circular discs varying from 1/3500 to 1/3200 of an inch in diameter and about 1/12400 of an inch thick. They are composed of a colorless stroma filled in with semifluid h[ae]moglobin and other matters. In most mammals the red corpuscles are circular, but in the camels, birds, reptiles, and the lower vertebrates generally, they are oval, and sometimes more or less spherical in form. In Amphioxus, and most invertebrates, the blood corpuscles are all white or colorless.
