  1. COMPLETE BLOOD COUNT

  2. COMPLETE BLOOD COUNT “A basic screening test that evaluates the cells that circulate in blood.” A complete blood count (CBC), also known as full blood count (FBC) or full blood exam (FBE) or blood panel.

  3. USES Screen for a wide range of conditions and diseases Help diagnose various conditions, such as anemia ,infection, inflammation, bleeding disorder or leukemia etc Monitor treatment that is known to affect blood cells, such as chemotherapy or radiation therapy Monitor the condition and/or effectiveness of treatment after a diagnosis is established

  4. A CBC is a panel of tests that evaluates the three types of cells that circulate in the blood and includes the following: • Evaluation of white blood cells • Evaluation of red blood cells • Evaluation of platelets

  5. EVALUATION OF WBCS • White blood cell (WBC) countis a count of the total number of white blood cells in a person's sample of blood.  All the white cell types are given as a percentage and as an absolute number per litre. • White blood cell differential may or may not be included as part of the panel of tests. It identifies and counts the number of the various types of white blood cells present. The five types include neutrophils, lymphocytes,monocytes, eosinophils, and basophils.

  6. NORMAL RANGES WBC: 4,000 – 10,000/cubicmm WBC DIFFERENTIAL: Neutrophil 40-75% Lymphocytes 15-75% Monocytes 1-10% Eosinophils 1-6% Basophils 0-2%

  7. ABNORMAL RESULTS OF WBC EVALUATION

  8. EVALUATION OF RBC • Red blood cell (RBC) countis a count of the actual number of red blood cells in a person's sample of blood. • Hemoglobinmeasures the amount of the oxygen-carrying protein in the blood. • Hematocritmeasures the percentage of a person's blood that consists of red blood cells. • Red blood cell indicesare calculations that provide information on the physical characteristics of the RBCs: • (RDW),which may be included in a CBC, is a calculation of the variation in the size of RBCs. • Mean corpuscular volume (MCV)is a measurement of the average size of RBCs. • Mean corpuscular hemoglobinis a calculation of the average amount of oxygen-carrying hemoglobin inside a red blood cell. • Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average percentage of hemoglobin inside a red cell. • reticulocyte countwhich is a measurement of the absolute count or percentage of young red blood cells in blood.

  9. NORMAL RANGES

  10. Evaluation of platelets The platelet count is the number of platelets in a person's sample of blood. Mean platelet volume (MPV) may be reported with a CBC. It is a calculation of the average size of platelets. Platelet distribution width (PDW) may also be reported with a CBC. It is a measurement of the variation of platelet size.

  11. NORMAL RANGE • Platelet count : 140,000 to 450,000 /cubic mm • Mean platelet volume: 7.5 – 11.5 fL • Platelet distribution width:10% - 17.9%

  12. IMPORTANCE OF CBC TEST IN DENTISTRY

  13. Reviewing clinical laboratory test results about a patient's condition can provide valuable information for • Diagnosis and management of orofacial conditions • Guidance on assessing the patient's ability to tolerate the proposed dental treatment • A prognosis based on a particular treatment

  14. EVALUATION OF WBC • when a patient is being treated with a medication that suppresses WBC production (such as antineoplastic agents), the patient is at a greater risk for postoperative infection, and dental treatment should be deferred until the WBC result is back to normal. • For invasive dental treatment, perioperative antibiotics are indicated in patients with ANC less than 1,000 cells/mm3 in order to minimize the risk of infection. When the ANC falls below 500 cells/mm3, intravenous antimicrobial therapy may be necessary to prevent sepsis resulting from invasive dental treatment.

  15. EVALUATION OF RBC • Patients with polycythemia may experience orthopnea in the dental chair, dizziness, headache, red facial coloring, and dyspnea. • Hgb and Hct are necessary parts of the assessment for anemias and in patients with burning mouth disorders and aphthous stomatitis. • Differ routine dental treatment in Patient with severe anemia

  16. EVALUATION OF PLATELETS • Bleeding disorders or bone marrow diseases, such healthcare provider to determine as leukemia, require the dental the number of platelets present and/or their ability to function correctly prior to invasive surgery. • Minor dentistry: counts should be greater than 50,000/cubicmm
