interpretation more difficult in some cases. Blood

counts of various types have been used

for clinical purposes since the 19th century.

MANUAL AUTOMATEDBlood Count Blood Count

Faster

An automated analyzer

is used

Precise in counting but

could be erroneous

when it comes to

abnormal blood cells.

RED BLOOD CELL COUNT

6/20

RBC COUNT

Red blood cell count

6

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.

Normal Ranges*:Male: 4.7-6.1 million/L

Female: 4.2-5.4 million/L* Based on USA records

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

HEMATOCRIT

11/20

HCT ValueHematocrit Value

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

PLT COUNTPlatelet count

13

Platelets help to stop bleeding by formingblood clots.

Measures the number of platelets, which are

important for blood clotting.

Normal Ranges*:150-400 thousand/L

* Based on USA records

16/20

WBC COUNTWhite blood cell count

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,

neutrophils, eosinophils, and basophils.

Normal Ranges*:4,500-10,000 cells/L

* Based on USA records
