Trend #1: Lateral Flow Immunoassay (LFI)
Shan, S., Lai, W., Xiong, Y., Wei, H., and Xu, H. (2015) Novel Strategies To Enhance Lateral Flow Immunoassay Sensitivity for Detecting Foodborne Pathogens. Journal of Agricultural and Food Chemistry. 63, 745−753. DOI: 10.1021/jf5046415.
This article talks about the simplicity, stability and sensitivity of conventional lateral flow immunoassay (LFI) device for the use of detecting foodborne pathogens. Foodborne pathogen has prevailed to cause disease and even death in individuals that has been exposed to bacteria thru food consumption. Therefore, the researchers in this paper examine, in great detail, how the conventional lateral flow immunoassay can be enhanced for stringent sensitivity as well as…
color may result. Some background color is normal. However, if colored background obscures test result, repeat the test.
No Color Development —If reference spot does not develop color, repeat the test

determine the absolute amount of drug present in the fluid being examined, which depends on when the drug was used and it’s half-life (Kapur 2001).
Immunoassay and chromatography, sometimes coupled with mass spectroscopy, are usually used first in toxicology testing. Immunoassays are often the test type employed first; they are not as specific, but can detect broad classes of drugs, and do not require lengthy sample preparation. Immunoassay permits small amounts of the drug or metabolite of the…
Methanol has been used as a solvent for cocaine extraction form banknotes2, 4, 9, 10. It was reported as a non-destructive method unlike other solvents like chlorinated solvents11 and acetonitrile1 as they were responsible for damage and partial destruction of the banknotes respectively.
Various sources of contamination affect the banknotes through handling it such as sweat, dust and so on. Additionally, banknotes are contaminated by different sources of drugs like amphetamine, nicotine and…
adults are estimated to have been taking cocaine in their life time according to the European monitoring centre for drugs and drug addiction (EMCDDA). Cocaine and its metabolites can be detected in hair, urine, saliva and blood1. It can be also be detected in surface water, waste water treatment plants2 and in banknotes3. Different methods have been reported for cocaine detection; enzyme immunoassay3, 4, 5, 6 , gas chromatography (GC) and liquid chromatography (LC), capillary electrophoresis…
key significance (Anderson, 2005). Test outcomes have the potential for blunder, and evaluated by a qualified master. The investigation of a natural example can take a few steps. The initial step, which is now and then circumvent, is the hypothetical or screening test, which empowers the examiner to distinguish a class of medications that may be available in a natural example. This stride trailed by the extraction of the medication on the other hand obscure substance from the natural grid,…
sensitivities, specificities as well as the predictive values and the optimal cut-off values can be found in Table 3.
As expected, the comparison of a LC-MS/MS determination of steroid hormones with immunoassays shows an over-determination by immunological methods, as already described by other authors [7,13,14]. All in all, a pronounced degree of analytical variability between the different tests can be detected. The best agreement was found between the LC-MS/MS and the LIAISON…
ever” which is called acute retroviral syndrome and it is the body normal response to HIV infection. The symptoms include fever, swollen glands, sore throat, rash, fatigue, headache, muscle pain, and joint aches and pain.
The most common test for HIV is an antibody screening test called immunoassay that searches for antibodies that the body makes against HIV. The immunoassay test is done in a laboratory or as a rapid test at a testing site location. The test is implemented with a blood sample…
In the immunoassays (RIA, ELISA, and CPB) enzymatic, radioactive or electrochemilumnicent markers are used. This markers coupled with an antibody for the quantification of 25(OH) D, then an antibody identify the 25(OH) D. These techniques might be more or less fully automated, which make high-throughput…
A urine test is quick and painless, the test uses a person’s urine to test for any illegal drugs, or prescription medications. The urine tests for alcohol, amphetamines, benzodiazepines, marijuana, PCP, and opioids (). Other form of drug testing are hair testing, perspiration testing, saliva testing, and blood testing ().
There are two types of urine drug test, they are the immunoassay gas chromatography/mass spectrometry, or GC/MS (Stang, D. (2015, October 5). The immunoassay is the most…
