Antibody Detection Is Critical for COVID-19 Diagnosis

Accurate and fast diagnosis of the causative SARS CoV-2 is important to isolate the patients with COVID-19 timely and stop the epidemics, as well as save people's lives. Viral nucleic acid detection using real-time polymerase chain reaction (RT-PCR) assay, which has been developed and used for detection of SARS-CoV-2 rapidly, remains the standard diagnosis of COVID-19.

Giemsa Stain Outperforms Urease Test for Helicobacter Pylori Diagnosis

More than 50% of the worldwide population is infected by Helicobacter pylori which is harbored in their upper gastrointestinal tract. Despite having chronic gastritis, most people infected by H. pylori are asymptomatic and have no specific clinical signs and symptoms. More...

Scabies Detected by Molecular Methods in Skin Scrapings

Scabies caused by Sarcoptes scabiei mites, is a highly contagious parasitic disease characterized by intense itching which is aggravated at night. Infections by scabies mites result in various skin eruptions consisting of papules, nodules, vesicles, and excoriated eczematous lesions due to scratching. More...

Urea Dissociation Tests Reduces SARS-CoV-2 IgM False-Positives

At present, the diagnosis of COVID-19 is mainly based on epidemiological history inquiry, laboratory testing, and chest radiology examination. Among these examinations, the detection of nucleic acid from SARS-CoV-2 is the direct evidence for COVID-19 diagnosis. More...
