Blood Cell Count



Blood Cell Count


A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia.
A complete blood count test measures several components and features of your blood, including:
  • Red blood cells, which carry oxygen
  • White blood cells, which fight infection
  • Hemoglobin, the oxygen-carrying protein in red blood cells
  • Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood
  • Platelets, which help with blood clotting
Abnormal increases or decreases in cell counts as revealed in a complete blood count may indicate that you have an underlying medical condition that calls for further evaluation.

Why it's done

A complete blood count is a common blood test that's done for a variety of reasons:
  • To review your overall health. Your doctor may recommend a complete blood count as part of a routine medical examination to monitor your general health and to screen for a variety of disorders, such as anemia or leukemia.
  • To diagnose a medical condition. Your doctor may suggest a complete blood count if you're experiencing weakness, fatigue, fever, inflammation, bruising or bleeding. A complete blood count may help diagnose the cause of these signs and symptoms. If your doctor suspects you have an infection, the test can also help confirm that diagnosis.
  • To monitor a medical condition. If you've been diagnosed with a blood disorder that affects blood cell counts, your doctor may use complete blood counts to monitor your condition.
  • To monitor medical treatment. A complete blood count may be used to monitor your health if you're taking medications that may affect blood cell counts.

Hemoglobin 


  Amount of this oxygen-carrying protein within red blood cells
   Men: 14 to 16 grams per deciliter
   Women: 12.5 to 15 grams per deciliter

Hematocrit


  proportion of red blood cells to the total blood volume
  Men: 42 to 50%
  Women:38 to 47%

Mean corpuscular volume 


 Stimate of the volume of red blood cells
    86 to 98 cubic micrometers

White Blood Cell Count 



  Precentages of the different types of white blood cells
  segmented neutrophils: 34 to 75%
  Band neutrophils: 0 to 8%
  Lymphocytes: 12 to 50%
  Monocytes: 15%
  Eosinophils: 0 to 5%
  Basophils: 0 to 3%

Platelet Count:



 Number of Platelets in a specified volume of blood.
    140,000 to 450,000 per microliter.

Antibiotic Sensitivity Test

Antibiotic Sensitivity Test Antibiotic sensitivity  or  antibiotic susceptibility  is the  susceptibility  of  bacteria  to  antibiotics . Because susceptibility can vary even within a  species  (with some  strains being more  resistant  than others),  antibiotic susceptibility testing  ( AST ) is usually carried out to determine which antibiotic will be most successful in treating a bacterial infection  in vivo .  Testing for antibiotic sensitivity is often done by the  Kirby-Bauer method ( agar diffusion test ) . Small wafers containing antibiotics are placed onto a plate upon which bacteria are growing. If the bacteria are sensitive to the antibiotic, a clear ring, or zone of inhibition, is seen around the wafer indicating poor growth. Ideal antibiotic therapy is based on determination of the aetiological agent and its relevant antibiotic sensitivity. Empiric treatment is often started before laboratory microbiological reports are available when treatment sho

Urine Culture

Urine Culture A urine culture is a test that can detect bacteria in your urine. This test can find and identify the germs that cause a urinary tract infection (UTI). Bacteria, which typically cause UTIs, can enter the urinary tract through the urethra. In the environment of your urinary tract, these bacteria can grow rapidly and develop into an infection. Who is the test for? Urine cultures can identify the microorganisms, typically bacteria, which cause a UTI. UTIs are more common in females than males. This is because a woman’s urethra is shorter and much closer to the anus. Therefore, it’s much easier for bacteria from the intestines to find their way into the urinary tract. Bacteria ascend the urethra into the bladder, ureters, and kidneys, where they can develop into an infection. How is the test administered? The urine for a urine culture can be collected in several different ways. The most common method for collecting urine is the midstream clean-
