This is the case study Case #1: Chronic Call-offs: Community Hospital provides its employees 12 sick days per year. Sam, a staff nurse, has called in sick before the start of his shift five times in his first 7 months. There is no apparent pattern with regard to events on the unit, day of the week, or other factors. As nurse manager, you ask to speak to Sam. How do you handle the conference?

Catchphrases: standard of chemical immunoassay, protein immunoassay test Protein IMMUNOASSAYS (EIA) Protein immunoassay (EIA) Presentation Protein immunoassay (EIA) or chemical connected immunosorbant test (ELISA) is an effective strategy utilized for identifying and evaluating antigens and antibodies in clinical examples. It is generally utilized as a part of clinical research facilities for determinations, anticipations and for checking insusceptible reactions. The point of this paper is to abridge the guideline of this method and to plot the fundamental kinds of catalyst connected immunosorbant test (ELISA) and its application in clinical labs. In this manner, it will talk about the use of this framework in the hematology field. Standards The general rule of this method depends on the authoritative of conjugated catalyst particle with particular antibodies to recognize and evaluate the nearness of either antigens or antibodies in the test. This is trailed by including proper vapid substrate which catalyzes the collaboration complex to deliver an unmistakable shaded item. There are numerous chromogenic substrates utilized as a part of ELISA system yet the most widely recognized are basic phosphatase (AP) and horseradish peroxidase (HRP). The final result can be dictated by utilizing spectrophotometer and the force of shading is straightforwardly relative to the nearness of either antigens or antibodies in the test tests. Sorts There are a few sorts of ELISA which include: backhanded, sandwich, focused, chemiluminescence and elispot test. Backhanded ELISA can be utilized to identify the antibodies that are available in patient's serum. With this technique, patient's serum containing antibodies is added to the microtitre wells which are covered with the antigen and the force of the end shading item is straightforwardly corresponding to the measure of antibodies that are available in the patient's example. (KUBY) Figure1. Represent the diverse sorts of ELISA to identify either antigen or immune response. The second kind of compound connected immunosorbant measure is called sandwich ELISA, in which the objective antigen that will be identified must be situated between two antibodies. The antigen of intrigue that is available in the clinical example is added to a microtitre wells which is covered with the counter acting agent and the finished result is dictated by spectrophotometer to quantify the measure of antigen in the clinical sample.(DIAGNOSTIC MICRO. BOOK) Figure1. The advancement of biotechnology has turned out to be across the board and one case of its encouraging is the alteration of ELISA by utilizing chemiluminescence substrate as opposed to chromogenic substrate to expand the affectability of the response. With this strategy, chemilumescence (CL) substrate and some improving specialists, which can tie a counter acting agent or antigen in the response, are utilized to make light emanations which can be estimated by particular spectrometry. This approach has been utilized to analyze a few kinds of tumor sickness, and measure various mixes at low fixation (Baeyens et al. 1998). Another case of ELISA adjustment is catalyst connected immunospot (ELISPOT) test. It is a quantitative method frequently used to distinguish cytokines that are emitted from single cell in light of the antigen. Amid the hatching time frame, the cytokines of intrigue is discharged and caught by immobilized hostile to cytokines on the microtitre plate. In the wake of washing them and including named against cytokines immune response and substrate, the end shading item shows as an "impression" around every one of the emitting cells, which can be assessed. This system has extraordinary potential for observing insusceptible reactions (Cox, Ferrari and Janetzki 2006). Moreover, touchy ELISPOT examine can identify low level of discharged IFN-? contrasted and other IFN-? measures (Lion et al. 2009). APPLICATION There are numerous utilizations of catalyst immunoassays in clinical research centers and the biggest application is identified with the discoveries of infections. For instance, the screening and analysis of hepatitis infection is routinely utilized as a part of the lab. These incorporate the location of HBsAg and HBeAg by coordinate ELISA, against HBc immunizer and hostile to HBe counter acting agent by aggressive ELISA and hostile to HBs neutralizer by aberrant ELISA (Tsitsilonis et al. 2004).What is more, ELISA can distinguish HCV antibodies in serum tests as screening tests and the positive examples are acclimated by sub-atomic HCV RNA (Erensoy 2001). The gainful impact of utilizing a catalyst immunoassay in clinical hematology is that it can distinguish alloantibodies in patients who much of the time get platelet transfusions for remedial purposes. It has been exhibited that ELISA is more delicate to the recognition of alloantibodies than different immunoassays, for example, lymphocytotoxic test (LCT) and the platelet immunofluorescence test (PIFT), and it is performed in a brief timeframe (Levin et al. 2003). Moreover, catalyst immunoassays can identify against platelet antibodies, platelet related IgG (PAIgG) , HLA and circling antibodies in patients with Idiopathic thrombocytopenic purpura (ITP) (Schiffer and Young 1983). There are a few bits of confirmation which propose that a pervasive herpes infection, specifically Epstein-Barr infection (EBV), is ensnared in numerous kinds of lymphoma, for example, Hodgkin's ailment and Burkitt's lymphoma, so the early discovery of EBV antigen particular T cells is basic and hence ELISPOT examine can be utilized to break down T cell reactions (Yang et al. 2000). Another of its element is identified with gained von Willebrand disorder, which is caused via autoantibodies against von Willebrand factor (vWF). This assumes a basic part in hemostasis and is portrayed by drawn out seeping because of the imperfection in vWF movement. Identification of hostile to vWF immune response can be performed by ELISA (Mohri 2003), and (Stewart et al. 1997) say that aggressive ELISA is a valuable strategy in the location of hostile to vWFA antibodies in a clinical examples. Notwithstanding the advantages of ELISA in the identification of HLA class I particular antibodies, it is less delicate than stream cytometry, so before platelet transplantation, stream cytometry must be utilized (Worthington et al. 2001). Despite the fact that chemiluminescence immunoassay has incredible affectability in distinguishing HBsAg in blood benefactor tests, it has less affectability than the polymerase chain response (PCR)(Sato et al. 2001), so to expand the wellbeing of blood from HIV-1 , HCV, and HBV, the nucleic corrosive intensification strategy (NAT) has been connected for the screening of blood benefactor tests (Weber, Mühlbacher and Melchior 2005). CONCLUSION Catalyst Immunoassay is a standout amongst the most huge strategies to have been utilized as a part of clinical research facilities to break down the antigen-counter acting agent response in a brief timeframe. It is delicate to screening a substantial number of clinical examples and hence has been application>GET ANSWER
