For lockbox instructions and Q&A, select Instructions for Use. 2 In 2006, the World Health Organization recommended that if the CD4 value is between 200 and 350 cells/μL, the decision to begin ART should depend on clinical stage of disease but definitely should be initiated before the CD4 count drops to less than 200 cells/μL. What role does IgG4 immunohistochemical staining play? We treat all elevated troponins as critical values that necessitate a phone call to the ordering physician and documentation on the patient's chart.

Sample is then drawn into a capillary glass tube. If dry ice is used, this should be noted on the cardboard box label, and the lid should not be sealed with tape. Whole blood specimens collected in EDTA tubes should be held at ambient temperature, but always less than 30°C. Q. I know that a molecular test detects nucleic acid and an antigen test detects viral protein, but how do they compare for clinical use and which is better? Is it acceptable to report out the automated white blood cell value as well as the corrected WBC? The patient's sample has been drawn in sodium citrate, EDTA K2, sodium heparin, and warm saline replacements, and a true platelet count cannot be obtained. Red and gold tops contain siliceous substances that activate the clotting cascade. These regulations include restrictions on the volume of formalin that can be shipped in a container (< 1 L in total and < 30 mL per jar) and that shipments with fresh tissue samples are clearly labeled as Biological Substance Category B. Free-flowing fluidics of a flow cytometer are vital to obtaining accurate test results. Samples that are severely lipemic or hemolyzed or that arrive unchilled later than two days after collection will not be accepted for OFA testing.

In this scenario, should I multiply all the indices and Hgb-related parameters with the dilution factor? Laboratory managers, supervisors, and testing personnel must understand and review the SOPs annually. Drugs or their metabolites are frequently concentrated in the urine in sufficient amounts to interfere significantly with urine assays. The skin is then punctured and the first drop of blood is wiped away. However, the conveniences of using plastic tubes far out-weigh the detractors.

April 2017—Our laboratory receives requests for breast predictive marker testing (estrogen receptor, progesterone receptor, HER2, Ki-67) on biopsies of bone metastases. Serum is usually the preferred specimen as it is a much cleaner matrix than plasma. In recent years, CD4 testing has expanded dramatically in resource-limited settings. We had a case of autoimmune hemolytic anemia with moderate spherocytes, but the MCHC was More ». Given that blood specimen collection tubes are in short supply, many laboratories may need to switch to an alternative collection tube manufacturer. To facilitate easy access, CD4 testing should be done as close to the patient as possible, ideally at the primary health care level or with a dedicated specimen referral system that is dependable and timely. 15 For proper labeling, packaging, and transportation of HIV-infected material in each country, protocols should adhere to local postal and courier service regulations for mailing a UN 3373 classified agent according to the current IATA guidance document.

Place the tube upright in a rack as quickly as possible after collection. Are there studies that have evaluated the true accuracy of a low platelet count via a manual dilution technique versus the many automated techniques, and is there a true value in performing the time-consuming manual platelet count? If a large panel is performed, should only a limited number of pathogen results be reported, even though the entire panel was performed? This article was developed as a guide to quality assurance CD4 testing in resource-poor settings. Procedures must be in place to ensure that patient confidentiality is maintained, the records are safe and secure, and a process is in place for disposal of the reports after a defined number of years. Plastic tubes are not only cheaper and safer but also allow for reduced centrifugation time and longer sample stability.

The sample should then be centrifuged at high speed (~1, 000 g; 2, 200 rpm) for 10 minutes. Some of my colleagues use an amended report with their own diagnosis changed.

If the sample has been collected into a serum separator tube, centrifugation will cause a layer of silicon gel to lodge between the packed cells and the serum.
