Laboratory diagnostics for HIV infection.
Laboratory diagnosis of human immunodeficiency virus (HIV) infection is fundamental for detecting and monitoring infection. Many diagnostic tools are available that are based on both detection of HIV-specific antibodies and virus antigen, or nucleic acid. As technology evolves, HIV testing assays are being improved providing better sensitivity and specificity. In this short review, we summarize...
متن کاملRapid, low-cost and instrument-free CD4+ cell counting for HIV diagnostics in resource-poor settings.
We present a novel, user-friendly and widely autonomous point-of-care diagnostic to enable HIV monitoring in resource-poor regions where the current pandemic is most prevalent. To specifically isolate magnetically tagged CD4+ cells directly from patient blood, the low-cost and disposable microfluidic chip operates by dual-force CD4+ cell magnetophoresis; whereby the interplay of flow and magnet...
متن کاملRapid diagnostics and appropriate antibiotic use.
Most antibiotics are prescribed by physicians lacking postgraduate training in infectious diseases. As such, prescribing physicians have varying levels of interest and sophistication in thinking about how to use molecular and microbiological data to inform therapeutic choices. Strategies designed to modify physician antimicrobial-prescribing practices must therefore choose simplicity over compl...
متن کاملRapid Development of Nucleic Acid Diagnostics
There has been a significant increase, fueled by technologies from the human genome project, in the availability of nucleic acid sequence information for viruses and bacteria. This paper presents a computer-assisted process that begins with nucleic acid sequence information and produces highly specific pathogen signatures. When combined with instrumentation using the polymerase chain reaction, ...
متن کاملCost analysis of rapid diagnostics for drug-resistant tuberculosis
BACKGROUND Growth-based drug susceptibility testing (DST) is the reference standard for diagnosing drug-resistant tuberculosis (TB), but standard time to result (TTR) is typically ≥ 3 weeks. Rapid tests can reduce that TTR to days or hours, but accuracy may be lowered. In addition to the TTR and test accuracy, the cost of a diagnostic test may affect whether it is adopted in clinical settings. ...
