Abstract:

We evaluated the diagnostic agreement of expired malaria rapid diagnostic tests (mRDTs) with non-expired mRDTs in a clinical setting in western Uganda. Expired mRDTs (SD Bioline Ag Pf/Pan and First Reponse Ag pLDH/HRP2) were administered to each participant in parallel with a non-expired mRDT serving as the reference. Of 200 participants, 21 (10.5%) tested positive and 179 (89.5%) tested negative for malaria. All tests up to 9-months post-expiration were valid and consistent with reference mRDTs. All mRDTs 10- to 12-months post-expiration were invalid. These preliminary findings support further research into the use of expired mRDTs in resource limited settings.

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Automated Microbial Diagnostics

Automated Microbial Diagnostics

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
