Complete blood count (CBC)
Hold information about the hematologic system and many other organs
Red blood cell (RBC) normal values
Males: 4.7 - 6.1
Females: 4.2 - 5.4
White blood cell count (leukocyte, count, white count) values
Normal value: 5000-10,000
Critical values : less than 2000 or greater than 30000
White blood cells decreased levels
Due to radiation; toxic and tradition of heavy metals, or chemical poisons; antineoplastic drugs
Hemoglobin(Hgb) values
Normal values:
Males: 14 - 18
Females: 12-16
Critical values: less than 7g/dL or greater than 21g/dl
What does hemoglobin do?
Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the bodies, tissues and returns carbon dioxide from the tissues back to the lungs
Hematocrit (Hct) values
Normal values:
Males 42-52%
Females 37 -47%
Critical values:
Less than 21% or greater than 65%
What does increased HCT do
Increased HCT can be caused by severe dehydration or COPD
Decreased HCT
Can mean, recent, bleeding or hemorrhage
Platelet count values
Adult reference value: 150,000-450,000
Critical values:
Less than 20,000 or greater than 1 million
Platelets (thrombocytes)
Are essential for coagulation of blood and maintaining homeostasis
Basis, metabolic panel (BMP) includes:
The panel includes sodium, potassium, chloride, carbon dioxide, glucose, BUN, creatinine, calcium
Sodium (Na+) values
Normal values: 136-145
Critical values: less than 120 or greater than 160mEq/L
It is most abundant in plasma
Potassium(K+) values
Normal value:
3.5-5.0 meEq/L
Critical values:
Less than 3 or greater than 8 mEq/L
Potassium(k+) function
•helps nerves to function& muscles to contract
•It is most noted in cardiac function
Calcium (Ca+) values
Normal value:
9.0 - 10.5
Critical value:
Less than 6 or greater than 13 mg/dL
chloride(Cl-) values
Normal levels:
98 -106 mEq/L
Critical levels:
Less than 80 or greater than 115 mEq/L
