HPV Test with Cytology Adds Little Diagnostic Value

The main goal of cervical screening programs is to detect and treat precancer before cancer develops. Human papillomavirus (HPV) testing is more sensitive than cytology for detecting precancer. More...

Molecular Automation Is Changing Clinical Laboratories

Most mid-career laboratory medicine professionals find it hard not to recall the days when DNA had to be extracted manually and polyacrylamide gels were mixed by hand without also reflecting on how fast things have changed. More...

Urine Test Developed for Accurate TB Detection

An accurate screening test for active pulmonary tuberculosis (TB) is urgently needed for patients who are not co-infected with human immunodeficiency virus (HIV). Worldwide, TB is one of the most prevalent bacterial infections, with the highest mortality in developing countries. More...

System for Identification of Filamentous Fungi Evaluated

The utilization of matrix-assisted laser desorption/ionization – time of flight (MALDI-TOF) mass spectrometry has the potential to speed up and improve the accuracy of identification of filamentous fungi. More...

Microscope-Based AI Identifies Bacteria Accurately

Microscopes enhanced with artificial intelligence (AI) could help clinical microbiologists diagnose potentially deadly blood infections and improve patients' odds of survival. More...

Image: This \"classic\" bullseye rash is also called erythema migrans. A rash caused by Lyme disease does not always look like this and approximately 25% of those infected with Lyme disease may have no rash, hence the need for new diagnostic tests (Photo courtesy of James Gathany/CDC).

New Lyme Disease Tests Offer More Accurate Detection

Lyme disease is the most common tick-borne infection in North America and Europe. There are currently over 300,000 cases of Lyme disease annually in the USA alone and the disease is increasing and spreading into new regions. More...

Researchers Decode Toxoplasmosis’ Control of Immune Cells

The infection toxoplasmosis is caused by the parasite Toxoplasma gondii and is widely spread. It is estimated that 30%-50% of the global human population are carriers. Cats are the parasites' main host, but the infection is also spread among other animals, including humans. More...
