Description White cell counts are usually performed using an automated instrument, but may be done manually using a microscope and a counting chamber, especially when counts are very low, or if the patient has a condition known to interfere with an automated WBC count. Do you have PowerPoint slides to share? If so, share your PPT presentation slides online with PowerShow. Although exact count is possible only through automated analysers or manual Neubauer chamber, blood smears can give a fair assessment about the count and whether it is abnormally low or high. Equation: Absolute Neutrophil Count = (% of neutrophil type * total WBC Count) / 100 To be honest, this sounds to me like cutting your grilled cheese sandwich into triangles or squares. The estimation of platelet count from blood smears must be systematic each time the automated count is erroneous because even the most expensive and most effective machine is not able to replace human judgement [1-3]. Chemistry tests must be ordered separately for body and synovial fluids. blood sample using sodium citrate as the anticoagulant. White blood cells fight infections, and protect our body from foreign particles, which includes harmful germs, and bacteria. The two most widely used methods for determining bacterial numbers are the standard, or viable, plate count method and spectrophotometric (turbidimetric) analysis. A thick slide (glass or plastic) has an area cut into its surface that will hold precise volumes of bathing fluid. Initially, the original Coulter Counter counted and measured only red blood cells.
