3.2 Laboratory Equipment for Manual Counting
Laboratory equipment for manual platelet counting includes a microscope‚ counting chamber (e.g.‚ hemocytometer)‚ pipettes‚ and dilution equipment. The microscope enables visualization of platelets‚ while the counting chamber provides a measured space for accurate enumeration. Pipettes ensure precise sample measurement‚ and dilution equipment prepares the blood sample for counting‚ minimizing errors and ensuring reliable results in canine platelet analysis.
Step-by-Step Procedure for Manual Platelet Count
The process involves blood sample preparation‚ dilution‚ and loading into a counting chamber. Platelets are then examined microscopically‚ counted‚ and results calculated for accurate platelet enumeration.
4.1 Blood Sample Preparation
Blood sample preparation is a crucial step in manual platelet counting. Collect blood into EDTA tubes to prevent clotting‚ mix gently‚ and ensure proper anticoagulant ratio. Allow the sample to stand at room temperature for 30 minutes before processing. Avoid prolonged storage to maintain platelet viability. Proper handling prevents clotting and ensures accurate results.
4.2 Dilution Techniques
Dilution is critical for accurate manual platelet counting. Mix 1 part blood with 1 part diluent‚ such as ammonium oxalate‚ to prevent clotting and ensure even distribution. Gently mix to avoid air bubbles‚ which can distort results. Proper dilution ensures the sample aligns with the counting chamber’s volume‚ providing a standardized count. Accurate dilution is essential for reliable platelet count results.
4.3 Counting Chamber Setup
The counting chamber is a specialized microscope slide with a built-in grid. Load the chamber with the diluted blood sample using a pipette‚ ensuring no air bubbles form. The grid helps in systematically counting platelets across predefined areas. Proper alignment and cleanliness of the chamber are crucial for accurate results. Allow the sample to settle before examination under the microscope. Always ensure the chamber is free of debris for optimal visibility.
4.4 Microscopic Examination
Under the microscope‚ platelets appear as small‚ round‚ and refractile cells. Use a magnification of 40x to identify them within the counting chamber grid. Count platelets in multiple large squares to ensure accuracy. Record the number of platelets observed and calculate the average. Ensure consistent focus and illumination for clear visualization. Avoid counting debris or overlapping cells to maintain precision in the manual count.
4.5 Calculation and Recording Results
After microscopic examination‚ calculate the platelet count using the dilution factor and the counting chamber grid. Multiply the average count by the dilution factor to determine the platelets per microliter. Record the results accurately‚ ensuring precision and clarity. Document the date‚ time‚ and technician’s name for traceability. Adhere to laboratory protocols for consistent and reliable outcomes‚ maintaining detailed records for future reference and clinical decision-making.
Factors Affecting Platelet Count Accuracy
Factors such as improper sample handling‚ delayed analysis‚ and technician variability can significantly impact the accuracy of manual platelet counts‚ requiring strict adherence to standardized protocols for reliable results.
