![]() ![]() If your urine contains blood it may make it look red or brown.Īcidity (pH): The pH level indicates the acid levels of urine. Cloudiness or an unusual odor may indicate an infection. Your urine sample will be checked for appearance. The type of rapid test used is dependent on the patient population and the goals of providing a rapid test result. Malarial falciparum and vivax antigen testing is rapid diagnostic tests used for detecting malaria antigens (proteins) in a person's blood and indicate a positive result by a color change on the testing strip also known as "dipstick" tests. Early diagnosis and treatment are crucial as serious complications, including severe intestinal bleeding or perforation, can develop within a few weeks of infection. This test is ordered when symptoms such as high fever, abdominal pain, diarrhea or constipation, fatigue, headache, weight loss, and rashes. The Widal test is one method that may be used to help make a presumptive diagnosis of enteric fever, also known as typhoid fever. This test is carried out in patients suffering from the signs and symptoms consistent with dengue such as fever or chills during the acute phase. This test is carried out in patients suffering from the signs and symptoms consistent with Chikungunya such as fever or chills during the acute phase.ĭengue antigen NS1 test is used for the diagnosis of dengue antigen in serum or plasma collected from patients. In case of signs or symptoms of conditions affecting red blood cell production.Ĭhikungunya IgM test is used for the diagnosis of chikungunya antibodies in serum or plasma collected from patients. In case the results of complete blood count or WBC differential is abnormal. In case of signs or symptoms of anemia such as weakness, fatigue, pale complexion, unexplained jaundice, and enlargement of the spleen. The peripheral smear examination is done: The peripheral smear examination (P/S) is also known as blood smear, is done to evaluate the different components of the blood. These antibodies are produced against the outer membrane protein (OMP) of Salmonella typhi. The presence of IgM antibodies indicates a recent infection while the presence of IgG antibodies indicates a remote infection. This protocol is a substudy of 04-068.The Typhi dot test measures IgM Antibody against Salmonella typhi. The RDT study will involve evaluation of the cohort over 12 months, beginning in approximately the third quarter of 2005. As part of the on-going longitudinal drug efficacy trial, probability sampling was used to select a random sample of 600 children, who will be followed for three years for all their health-care needs. In the RDT study, over a one-year period, study participants' blood samples will be evaluated with the current gold standard for malaria diagnosis (microscopy) as well as two types of RDT whenever they present with a new fever episode (the first fever after study enrollment, or a fever that occurs more than 14 days after the patient's most recently diagnosed episode of malaria). ![]() Study subjects in this RDT study will have already been enrolled in a larger on-going longitudinal study of antimalarial drug efficacy, tolerability, and safety that began at the Kampala study site in late 2004. This longitudinal study's objectives are (1) to evaluate the clinical performance (sensitivity, specificity, positive and negative predictive values) of RDTs, as compared with presumptive diagnosis and microscopy, for the diagnosis of malaria in children in Kampala, Uganda, and (2) to identify host and test factors that lead to false positive and false negative RDT results by comparison with polymerase chain reaction (PCR) analysis. Rapid diagnostic tests (RDTs), based on detection of Plasmodium antigens, may represent a more practical diagnostic tool than traditional light microscopy. The need for an accurate, simple, and inexpensive method to diagnose malaria has become increasingly urgent. Malaria remains one of the most devastating infectious diseases, causing high morbidity and mortality especially in sub-Saharan Africa. ![]() Why Should I Register and Submit Results?. ![]()
