Principle The Coulter AcT2 Hematology Analyzer performs a Complete Blood Count (CBC), Platelet Count, and a Three-Part Differential. Whole blood is aspirated, diluted, and then divided into two samples. One sample is used to analyze the red blood cells and platelets while the second sample is used to analyze the white blood cells and hemoglobin. Electrical impedance is used to count the white blood cells, red blood cells, and platelets as they pass through an aperture. As each cell is drawn through the aperture, a change in electrical resistance occurs generating a voltage pulse. The number of pulses during a cycle corresponds to the number of cells counted. Hyt 700 Manual on this page. The amplitude of each pulse is directly proportional to the cell volume.

Lyse reagent is added to the diluted sample and used to count the white blood cells. After the white blood cells have been counted and sized, the remainder of the lysed dilution is transferred to the Hgb Flow Cell to measure Hemoglobin concentration. 2015 Saturn Sl2 Owner Manual. The AcT2 uses electronic sizing to determine a three part automated differential from the WBC histogram.

The percentage and absolute counts are determined for lymphocytes, neutrophil, and monocytes. The AcT diff2 analyzer has two operating modes: Open Vial Whole Blood and Closed Vial Whole Blood. Volkswagen Lt28 Manual. Whole blood samples can be analyzed in either mode. Prediluted samples can be analyzed at the Open Vial Station. Specimen Collection and Handling HANDLE BLOOD AS A POTENTIAL BIOHAZARD CAPABLE OF TRANSMITTING INFECTION. ALWAYS WEAR PROTECTIVE GLOVES AND LAB COAT WHEN PROCESSING SPECIMENS. Draw specimen in into a lavender-top vacutainer tube containing K2EDTA.

Thoroughly mix blood with EDTA anticoagulant. If hemolysis or small clots are observed, discard specimen.

Mix venous blood sample at least 8 times by hand inversion. Gently turn capped sample upside down then back straight up. Alternatively, use a mechanical mixer for at least 5 minutes. Do not test samples that are incorrectly filled or that are clotted. If hemolysis or small clots are observed, discard specimen. Analyze venous blood samples within 24 hours of collection.
