DIAGNOSTIC PROCEDURES: COMPLETE BLOOD COUNT

DIAGNOSTIC PROCEDURES: COMPLETE BLOOD COUNT

1. HEMATOCRIT (HCT)

   • measurement of the percentage of red blood cells in whole blood.
   • Normal Findings:
     • Adult males: 42% - 52% Adult females: 36%- 48 % Neonates: 55%-68% Neonates 1 week: 47%-65% Infants age 1 month: 37% - 49% Infants age 3 months:30%-36% Age 1 year: 29%-41% Age 10 years: 36%-40%

2. HEMOGLOBIN (HGB)

   • the main transport of oxygen and carbon dioxide in the blood.
   • Normal Findings:
     • Adult male: 14-17.4g/dl Adult female: 12-16 mg/dl Normal Newborn Range: 14 - 20 %

3. RED BLOOD CELLS COUNT (RBC)

   • RBC or erythrocyte count is a part of complete blood count which is used to determine the number of RBCs in a microliter or mm3 of whole blood.
   • Normal Findings:
     • Normal Adult Male Range: 4.5 -5.5 mill/uL Normal Adult Female Range: 4- 5. mill/uL Lower ranges are found in children, newborns, and infants Full- term neonates: 4.4. – 5.8 mill/uL at birth, decreasing to 3-3.8 mill/uL at age 2 months and increasing slowly thereafter. Children: 4.6- 4.8 mill/Ul

4. RED CELL INDICES

   • With the use of RBC count, HCT and Hb results, red cell or erythrocyte indices can be determine (the size, Hb concentration and Hb weight of an average RBC).
   • Normal Findings:
     • MCV -size MCH –concentration of hemoglobin per RBC MCHC –concentration of hemoglobin per volume of RBC
       • 84-99 um3 26-32 pg/cell 30-36 g/dl

5. WHITE BLOOD CELLS COUNT (WBC)

   • Granulocytes Neutrophils Eosinophils Basophils
     • Nongranulocytes Lymphocytes Monocytes
   • Normal Findings:
     • WBC count: 10,000/Ul N:54%-75% E:1-4% B:0-1% M:2-85 L:25-40%

6. PLATELET COUNT

   • Elevated levels suggest stimulation of the bone marrow where the cells are produce and decreased levels may indicate an immune system failure, drug reactions, DHF, B12, or folic acid deficiency.
   • Normal Findings:
     • Normal Adult Range: 130 - 400 thous/uL
