CBCCOMPLETE BLOOD COUNT

It provides detailed information about three typesof cells in ones blood. Conventional preference
ranges will be adequate for diagnostic purposes,
but a number of pitfalls may make
interpretation more difficult in some cases. Blood

for clinical purposes since the 19th century.

Red blood cells carry oxygen to andremove waste products from the bodystissues.
Measures the number of red blood cells,
which pick up oxygen from the blood
and deliver it to tissues throughout the
body.

HgB ValueHemoglobin Value

Hemoglobin gives red blood cells their color and carriesoxygen from the lungs to the tissues and takes carbon
dioxide (the waste products) from the tissues to the lungs.
Beyond or below the normal range have
the same connotation as the ones from
RBC count.
Normal Ranges*:Male: 13.8-17.2 g/dL
Female: 12.1-15.1 g/dL* Based on USA records

11
The hematocrit is the percentage of redblood cells in relation to your total
blood volume.
Beyond or below the normal range have
the same connotation as the ones from
RBC count.
Normal Ranges*:Male: 40.7%-50.3%
Female: 36.1%-44.3%* Based on USA records

These cells are the mobile units ofthe bodysinfection-fighting system.
Measures the total number of white blood cells, which
defend the body against infection; there are several different
types of white blood cells: lymphocytes, monocytes,
