This updated manual provides a basic understanding of the principles of laboratory and point-of-care (POC) testing in the context of screening and diagnostic approaches, as well as antimicrobial susceptibility testing, as components of sexually transmitted infections (STIs) control. As with previous... editions, this manual covers each disease in a separate chapter which provides detailed information on specimen collection, transport and laboratory testing. Two useful annexes covering media, reagents, diagnostic tests and stains (recipes) and laboratory supplies are included at the end of the manual.

The WHO standard: Universal access to rapid tuberculosis diagnostics sets benchmarks to achieve universal access to WHO-recommended rapid diagnostics (WRDs), increase bacteriologically confirmed tuberculosis and drug resistance detection, and reduce the time to diagnosis. WHO-recommended rapid diagn...ostics are highly accurate, cost-effective, reduce the time to treatment initiation, and impact patient-important outcomes.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

TECHNICAL SPECIFICATIONS FOR TEST SELECTION ESSENTIAL IN VITRO DIAGNOSTIC TESTS FOR SARS-COV-2
This document provides brief information answering common questions regarding COVID-19 diagnostic tests and how to prioritize them to the patients most in need.
The Interim Guidance on Cholera Rapid Diagnostic Tests (RDTs) by the Global Task Force on Cholera Control (GTFCC) provides recommendations for using RDTs to detect cholera in areas with limited laboratory capacity. It highlights the advantages of RDTs, such as rapid detection (within 30 minutes), ea...se of use by non-laboratory personnel, and their role in early outbreak identification and surveillance. However, it emphasizes that RDTs should not replace culture or PCR testing, as they vary in sensitivity (58-100%) and specificity (60-100%). The document advises on proper test selection, storage, training, and integration into national surveillance systems to enhance cholera response efforts.
