 Synonym - Description - Specimen - Method &Indication 




Synonym  :  CBC

  Description    

A Complete Blood Count  (CBC) is a group of tests used for basic screening purpose 
It is probably the most widely ordered laboratory test .Results provide the enumeration of the cellular elements of the blood , measurement of RBC indices , and determination of cell morphology by automation and evaluation of  stained smears . the results can provide valuable diagnostic information regarding the overall health of the patient and patient's response to disease and treatments . ok  
 
Specimen
 Whole blood on EDTA .Whole blood on heparin may be used , but the following automated values may not be reported : white blood cell (WBC) count , WBC differential , platelets count, and mean platelets volume 

METHOD 

Automated , computerized multichannel    analyzers . the tests includes hemoglobin  , hematocrit ,red blood cell (RBC) count , RBC morphology , RBC indices , RBC distribution width index(RDW) , Platelets acount , platelet size , WBCs acount and WBC differential . the automated WBCs differential indentifies  and enumerates neutrophils,  lymphocytes , monocytes , Esinophils and Basophils 

Indications 

1- Detect hematologic disorder ,neoplasm,leukemia , or immunologic abnormality 
2 - Determined the presence of hereditary  hematologic  abnormality 
3 - Evaluate  known or suspected anemia 
4 - Monitor the effects of physical or emotional stress 
5 - Monitoring blood loss 
6 - Monitoring fluid imbalance 
7 - Monitoring hematological status during pregnancy 
8 - Monitoring progression of non hematological disorder such as cancer and renal disease 
9 - As part of a general physical examination , especially on admission to a health care facility  or before surgery

MICROSCOPIC URINALYSIS

MICROSCOPIC URINALYSIS   Methodology A sample of well-mixed   urine (usually 10-15 ml) is centrifuged in a test tube at relatively low speed (about 2-3,000 rpm) for 5-10 minutes until a moderately cohesive button is produced at the bottom of the tube. The supernatant is decanted and a volume of 0.2 to 0.5 ml is left inside the tube. The sediment is resuspended in the remaining supernatant by flicking the bottom of the tube several times. A drop of resuspended sediment is poured onto a glass slide and coverslipped.

Liver Enzymes

Liver Enzymes   Definition A liver enzyme is a protein that helps to speed up a chemical reaction in the   liver. Liver function tests are blood tests that are used to evaluate various functions of the liver - for example, metabolism, storage, filtration and excretion, which are often performed by liver enzymes. However, not all liver function tests are measures of enzyme function. • ALT - (alanine aminotransferase )   - was previously called SGPT is more specific for liver damage. The ALT is an enzyme that is produced in the liver cells (hepatocytes) therefore it is more specific for liver disease than some of the other enzymes. It is generally increased in situations where there is damage to the liver cell membranes. All types of liver inflammation can cause raised ALT.    • AST - (aspartate aminotransferase) which was previously called SGOT. This is a mitochondrial enzyme that is also present in heart, muscle, kidney and brain therefore it is less specific
