Examination
- Previously known as postanalytical phase
- Process in which the results of the testing are communicated to the health care provider or physician
Post-Examination

blood & blood forming tissues
Hematology
checks the hemoglobin level and the red cell count.
Hematocrit (Hct)
tests the value to rule out anemia.
Hemoglobin (Hgb)
used to measure the erythropoietic activity.
Red Blood Cell (RBC) count
checks the leukocyte response
White Blood Cell (WBC) count
used to monitor chemotherapy and radiation conditions.
Platelet (Plt ct) count
monitors changes in the appearance or quantity of specific cell types
Differential White Count (Diff)
shows the changes in RBC size, weight and Hgb content
Indices
gives the weight of the hemoglobin in the cell.
Mean Corpuscular hemoglobin (MCH)
shows the size of the cell.
Mean Corpuscular volume (MCV)
gives information on the concentration of the hemoglobin per unit volume of RBCs.
Mean Corpuscular hemoglobin concentration (MCHC)
measures the size differences of the RBCs
Red blood distribution width (RDW)
used to monitor liver disease.
Alanine amino tranferase (ALT)
checks levels especially for prenatal screening
Alpha-fetoprotein (AFP)
determines level to check obstructions and bone disease.
Alkaline phosphatase (ALP)
measures the level which could indicate cirrhosis and hepatitis.
Ammonia
checks the enzyme level which could indicate liver disease, cholesystitis, etc.
Amylase
performs most lab test for plasma, white blood, urine, etc.
Chemistry
measures the level which is indicative of liver dysfunction.
Aspartate Amino-Transferase (AST)
