How Can the QBC STAR Help Your Ebola Preparedness?
Screening of suspected Ebola cases optimally involves the use of complete blood count (CBC) analysis to screen for changes in components of the patient’s blood, such as low white blood cell counts manifest by lymphopenia and or neutropenia as well decreased platelet counts. Plasma loss and or bleeding may also affect the hemoglobin and hematocrit. Laboratory findings at admission may include leukopenia frequently with lymphopenia followed later by elevated neutrophils and a left shift. Platelet counts are often decreased in the 50,000 to 100,000 per microliter range.1
The QBC STARTM Dry Hematology Analyzer is a compact and easy to use hematology analyzer that brings the CBC parameters to the patient's physician at the point of care and can economically comply with the CDC recommendation to use dedicated medical equipment.2 With a 9-parameter complete blood count at the push of a button, the QBC STAR Dry Hematology Analyzer makes on-site monitoring of CBC parameters, including WBC's and Platelets, fast and effective. The QBC STAR disposable is also designed for reduced bio-hazard risk because the patient's blood is drawn directly into a capillary tube that is contained within a polycarbonate sleeve. After closure the blood containing capillary tube is analyzed within the polycarbonate sleeve which means the blood sample does not contact any other part of the system.3 In addition, the QBC STAR technology is also designed to send the CBC results, including the image of the sample, electronically to governing agencies and or central laboratory supervisors for review and compilation.4
Patients from countries currently affected by the Ebola outbreak who present with fever could have other potentially serious infectious diseases that should be considered in the differential diagnosis, including but not limited to malaria, typhoid fever, and bacterial infections such as pneumonia.1 In order to check for malaria and other hematoparasitic diseases, the blood sample from the QBC STAR tube may be examined with a Drucker Diagnostics Paralens Advance on a standard light microscope for the presence of malaria parasites.
