Acute kidney injury (AKI, previously referred to as acute renal failure) is a common and serious condition particularly among hospitalized patients with acute illness and those undergoing major surgery.It can be life-threatening but it can also be reversible. Clinically AKI is characterized by abrupt loss of kidney function resulting in a rapid decline in the glomerular filtration rate (GFR),water and electrolytes imbalance, and accumulation of nitrogenous wastes such as blood-urea nitrogen and creatinine

Risk factors and transmission: Hepatitis C infection is transmitted mainly through percutaneous exposure: injecting drug use, accidently needlestick injuries (Tohme and Holmberg, 2010), and procedures as renal dialysis and unscreened blood transfusions (Candotti et al., 2001), the latter has become rare due to routine screening for HCV (Boesecke, 2011). Most HCV infections occur in people who use unsterile injection and contaminated drug solutions (Nelson et al., 2011)

Drug screening, which is generally used in criminal situations, health care and the workplace has recently become more common. The ease of use and fast results have increased the use of immunoassays; however, these can cause false positive results. This can lead to severe consequences if they are not confirmed by secondary analysis, such as gas chromatography-mass spectrometry (GCMS). The drugs screened during this experiment were ketamine, methadone, diazepam, codeine and imipramine. This report

group B. The most definitive method for testing beta-hemolytic streptococci is the latex-agglutination method. Alternatively identification can be made by the ability of S. pyogenes to hydrolyze the reagent PYR causing it to turn bright red. Rapid immunoassay testing is also available in detecting group A streptococci. This method identifies group A antigens from throat swabs and because they are so fast, they are usually used in clinics and physician offices. However, a throat swab for “strep” culture

is essential to prevent hospital spread of infection. The aims were to determine the prevalence of CDI among cases of AAD in Zagazig University Hospitals, identify risk factors, and evaluate real-time polymerase chain reaction (PCR) and enzyme immunoassay (EIA), against toxigenic culture (TC). Stools were collected from 150 patients with AAD. They were tested for TC, toxin A/B EIA, and C. difficile tcdA/tcdB genes. Thirty four toxigenic C. difficile isolates were obtained (22.7%) out of the 150 patients

Current FT4 immunoassays are actually FT4 estimate tests that do not measure FT4 directly and are known to be sensitive to alterations in binding proteins. Generally the increase in serum thyroid binding globulin, free fatty acid concentrations and a decrease in albumin concentration in pregnancy results in a method-dependent decrease in serum fT4 concentrations with most common immunoassays[8]. However, even with current reference methods employing

DIAGNOSIS OF HCV 1. Serologic assays (indirect assays) Tests which detect anti-HCV are used to screen, and to diagnose hepatitis C infection. Enzyme Immunoassays (EIAs), Chemiluminescence Immunoassay (CIA) and Recombinant Immunoblot Assay (RIBA) are approved by the Food and Drug Administration (FDA) for clinical use (Colin et al., 2001). The specificity of current EIAs for anti-HCV is greater than 99%. False positive results are more likely to occur in low-risk populations, however false negative

She has made a huge difference for the best in this world. Her creation of the radio-immunoassay has helped people with type II diabetes and how to measure it. It lead to the discovery that diabetes is caused by an insufficient level of insulin in your bloodstream. RIA has many uses, including narcotics or drug detection, blood bank screening

Introduction Insulin is a peptide hormone secreted by the β-cells of the pancreas. It is secreted in response to glucose and secretion occurs in a biphasic pattern. Insulin testing is commonly indicated in the investigation of insulinomas, hypoglycaemia, diabetes, polycystic ovary syndrome, as well as a number of other conditions. The analysis of insulin is often restricted by strict pre-analytical recommendations. The Chemical Pathology Laboratory at Groote Schuur Hospital Laboratory receives blood

Environment must be perfect and an experienced scientists know how to perform the test. Since this test is complicated and must be done perfectly and must be done in experienced laboratories, this test is not available widely (CDC, 2012).The enzyme immunoassay and the tissue cytotoxin assay both test for toxins in stool specimens. These two tests must be tested before two hours of being collected or refrigerated in this time period because Clostridium difficile toxins degrade fast (Gould, 2010). EIA for
