Any positive drug test should always be confirmed with a secondary test such as GC-MS that detects and provides identification and levels of a specific compound.Learn More about Drug Testing: Drug Testing FAQsTable 1: Drugs Reported to Cause a False Positive Urine Drug Screen...
including OPSCC. Tests ideal for early-stage HPV-related cancers would be highly sensitive, specific, and capable of distinguishing between indolent viral infections and malignant tumors. As a minimally invasive test, HPVoncogenesin plasma could potentially be used for the identification of HPV ...
Full size image Identification of a public TCRβ clonotype from CBZ-SJS/TEN We investigated the CDR3 assemblies of TCRβ clonotypes in the samples of blister cells of patients with SJS/TEN. Preferential and oligoclonal TCRβ clonotypes were noticed in the blister samples of patients with CBZ-...

Some common cutting agents such as sugars have high boiling points and therefore are not volatilized to a large extent, and do not enter the column in appreciable quantities [107]. Some drug molecules are not suitable for identification with GC–MS given that they do not ionize, have limited...
Moreover, homology-based discovery, as well as comparative transcriptomics and HT mutagenesis screens, typically require the identification of an isolated strain that performs the modification of interest and its use as the basis for genetic manipulations and/or functional analyses. These two limitations...

The lack of registered drugs for nonalcoholic fatty liver disease (NAFLD) is partly due to the paucity of human-relevant models for target discovery and compound screening. Here we use human fetal hepatocyte organoids to model the first stage of NAFLD, s
There are different approaches to prioritizing genetic targets3,4,5. The identification of multiple genetic variants in a single gene that associate with the outcome of interest (an allelic series) and mimic a dose-response curve can provide a direct indication that a promising target has been se...
