A) It decreases the loss of gases from the specimen. The procedure requires a nurse to attempt a blood draw twice and, if not successful, ask another nurse, and then ask the nursing supervisor before finally calling the laboratory. If at all possible, a representative composite sample of the feed should be submitted from the suspect lot or shipment (ie, aliquots from the top, middle, and bottom of the feed container).

What kind of precision/accuracy/ normal range/patient sample/control testing do you recommend? Plastic containers, both bags and jars, are ideal: jars with metal tops should be avoided. Mid- to low-throughput systems, such as the FACSCount (BD Biosciences), Guava PCA (Millipore, Billerica, MA), and CyFlow (Partec, Gorlitz, Germany), have been successfully implemented at district hospitals and some larger primary health care facilities where 20 to 100 samples are tested daily. Be as gentle as possible, drawing the blood evenly. June 2017—Our analyzer reported nucleated red blood cells of six, with no cellular interference flag. Quality Management Systems Approach for CD4 Testing in Resource-Poor Settings | American Journal of Clinical Pathology | Oxford Academic. To avoid these preanalytical issues, stoppers are usually made from materials that are low-extractable.

How do you calculate RDW-SD and RDW-CV values in dimorphic anemia cases on the Sysmex XN-3000? Some laboratories accept urine samples with addition of a preservative such as boric acid, but clinicians should contact these labs for specific protocols. March 2017—Our hospital system is implementing Sysmex instruments with a focus on the accuracy of the absolute white blood cell values—use of the absolute neutrophil count and immature granulocytes with the WBC as markers for septicemia. All agencies involved in implementing CD4 testing must understand the needs of the laboratory and provide advocacy, guidance, and financial support to established CD4 testing sites and programs.

To insure proper sample handling and identification, please write legibly on tubes and accession forms. Are there guidelines on which organisms to include and how many times to test? What performance characteristics do you verify? Some tubes contain gel separator at the bottom of the tube which acts as a barrier between serum and clot or plasma and cells following centrifugation. Which method is preferred—a refractometer or an automated dipstick? The sample should be held at room temperature for 20–30 minutes to allow complete clot formation and retraction. 23050 treat automated and manual differentials equally? When a patient has a hematocrit level of ≥55 percent and a normal PT and APTT, do you still correct sodium citrate and ask for a redraw?
