Decreased or faulty red blood cell production, which is often due to deficiency of iron, vitamin B12 and folate, cancer, HIV/AIDS, or chronic inflammatory or bone marrow diseases.Blood loss caused by trauma, heavy menstrual bleeding, gastrointestinal bleeding, or other bleedings.The different causes of anemia can be divided into three groups: It is a condition in which the number of red blood cells or the availability of hemoglobin falls below the body’s physiological needs. POC hemoglobin testing: where and why?Īnemia is the most common blood disorder, affecting around 25 percent of the global population, 1 and it can be caused by poor nutrition or various diseases. Reliability includes traceability to established reference methods, regular quality assurance checks and continuous operator education. Accuracy and reliability are therefore the crucial characteristics for POC hemoglobin analyzers. It is vital for healthcare professionals working in these settings to be able to rely on the result given by the POC hemoglobin analyzer and not have to order a confirmatory test from the laboratory. It is ideal for use in settings where resources are poor, or there is a need for mobility and simplicity in field use, or where turnaround time (TAT) for the test result needs to be short, as in acute clinical situations. POC hemoglobin testing is often needed in settings where the use of a benchtop laboratory hematology analyzer is not practical. This situation is even less understandable when you consider that the main diagnostic, hemoglobin testing, is one of the most commonly used point-of-care (POC) tests, and one of the easiest to perform. Anemia is a condition that causes a high degree of personal disability but, historically, has lacked adequate resourcing in many public health systems.
