D. M. Wolk, et al. We use a "mock" humidity chamber (wet papertowels with a plastic cover) because we found during our validation that testing took too long without it. Verax is located at 377 Plantation Street, Worcester, MA 01608. The Verax Pan Genera detection (PGD) test (Verax Biomedical Incorporated, Worcester, MA) is an easy‐to‐use rapid immunoassay that has been licensed by the FDA as a point‐of‐use method for bacterial detection in apheresis and whole blood–derived PCs that have been previously tested with an approved culture‐based test. Object detection, one of the most fundamental and challenging problems in computer vision, seeks to locate object instances from a large number of predefined categories in natural images. It is the only test FDA-approved as a point-of-issue safety measure in addition to a quality control test. In the United States, INTERCEPT is the only FDA‐approved PRT for PLTs, and the Verax PLT PGD Test is the only rapid bacterial detection test cleared as a safety measure, which allows extension of dating to … The above pertinent published studies have been reviewed and no risk factors were identified that would affect the performance of this assay in our laboratory. Deep learning techniques have emerged as a powerful strategy for learning feature representations directly from data and have led to remarkable breakthroughs in the field of generic object detection.

Label 1 barcode on the collection tube, 1 barcode on the test requisition form, and 1 barcode on the biohazard bag. Performance not validated for use in other platele t samples. These antigens are present on bacterial cells at high copy numbers (>200,000 copies/cell). The Verax Platelet PGD ® test is a rapid immunoassay that detects antigens present on the surface of bacteria. The small number of bacteria present at collection makes traditional testing approaches used to detect blood contaminants such as viruses virtually impossible. It is particularly challenging to balance specificity at genus level with equal sensitivity towards each target species. rapid test to detect bacteria in platelet concentrates Amount: $126,817.00 Verax Biomedical Inc. proposes to develop a rapid, accurate, cost-effective screening test to detect a broad array of bacterial contaminants in stored human platelets.

Test as a Rapid Screening Method for Detection of MRSA in Nares. It is sensitive, simple, rapid and practical for use in the hospital transfusion service setting, providing results in approximately 30 minutes. 2009. The Verax Platelet PGD test is the first test cleared by the FDA as a Safety Measure within 24 hours of transfusion of leukoreduced apheresis platelets that have been tested by a growth-based QC method cleared by the FDA for platelet components. The PGD technology detects the presence of conserved antigens lipotechoic acid (LTA) and lipopolysaccharide (LPS) on Gram-positive (GP) and Gram-negative (GN) bacteria, respectively. View results online within 24-48 hours. Verax is the manufacturer of the Platelet PGD Test, the only test for bacterial contamination in platelets granted a Safety Measure claim by the FDA. STUDY DESIGN AND METHODS: Outdated (7- to 10-day-old) BCPs that tested negative during initial screening were assayed with BacT/ALERT and the Verax PLT Pan Genera detection (PGD) test, an immunoassay that detects Gram-positive (GP) and Gram-negative (GN) bacteria. None of them has been previ-ously validated in a diagnostic setting (9, 12). Multi-site infrastructure monitoring. The Platelet PGD Test is a simple, rapid, day of transfusion test for the detection of bacterial contamination in platelets and is based on Pan Genera Detection®(PGD) technology. In addition, actual growth patterns are highly biologically variable due to species, strain, isolate, lifecycle and inoculum size differences. It detects the presence of conserved antigens lipoteichoic acid (LTA) and lipopolysaccharide (LPS) found on aerobic and anaerobic GP and GN bacteria, respectively. The Company's first product is the Platelet PGD Test – a rapid test for the detection of bacterial contamination in platelets. The Verax Platelet PGD test is the first test cleared by the FDA as a Safety Measure within 24 hours of transfusion of leukoreduced apheresis platelets that have been tested by a growth-based QC method cleared by the FDA for platelet components. 13 It is the only rapid bacterial detection test cleared for use as a “safety measure” by the FDA. Little is known about how widespread the adoption of the PGD test is across US hospitals. Specializing in Platelet Bacterial Contamination Detection, Verax Biomedical's Platelet PGD (Pan Genera Detection) System Detects Bacterial Contamination in Cells & Tissues Intended for Transfusion & … The PCR test forms the basis of a number of tests that can answer many different medical questions that help physicians diagnose and treat patients. Verax's patented Pan Genera Detection (PGD) technology is ideally suited to address the need for rapid and practical tests for bacterial contamination, due to its unique and proven ability to detect a wide variety of possible bacterial contaminants quickly, cost effectively and with minimal labor.

Verax Biomedical is the Leading Developer of Rapid Tests for Platelet PGD (Pan Genera Detection), Allowing the Rapid Detection of Bacterial Contamination of Blood Components It is the first FDA cleared method for testing on the day of transfusion, offering the opportunity to address this significant risk to patient safety. Geographically distributed enterprises with multiple branch offices. The PGD test was performed on day of issue on apheresis PLTs released by collection centers as culture negative. For example, PCR tests can detect and identify pathogenic organisms in patients, especially those that are difficult to cultivate (for example, HIV and other viruses and certain fungi). The test can be used to extend the dating of apheresis platelets in plasma, the most common platelet type transfused in … Verax Biomedical is the producer of the Platelet PGD® Test, the only test for bacterial contamination in platelets granted a Safety Measure claim by the FDA.
