The detection of SARS-CoV-2 is based on the identification of viral RNA from respiratory samples by RT-PCR. Currently, the standard method for the detection of SARS-CoV-2 infection is the one that includes the nasopharyngeal swab, but there are other alternatives (nasal swab, oropharyngeal swab or saliva) whose sensitivity and specificity are under discussion.   Figure 1. Differences between nasal swab, nasopharyngeal swab and oropharyngeal swab.   However, the use [...]

The importance of sensitivity in COVID-19 testing

10 February, 2021|Categories: Awards, News|

The limit of detection of an RT-PCR test is the lowest detectable concentration of viral RNA that gives a positive result (in more than 95% of repeat measurements). A low detection limit indicates a higher analytical sensitivity, which means that the test can detect a positive result from a lower number of viral RNA copies per sample. The greatest benefit of tests with a low limit of detection [...]

For that purpose, there are different diagnostic tests for the detection of this disease. One of the most used, due to its specificity and high sensitivity, is the detection of the virus by PCR, in which the smear for the collection of [...]

Adherence study to the Gluten-Free Diet in celiac patients

The Central Hospital of Asturias has published a scientific article whose main objective is to analyze the adherence to the Gluten-Free Diet (GFD) in celiac patients. This clinical study has been carried out by the determination of Gluten Immunogenic Peptides (GIP) in feces and the completion of a dietary questionnaire. During the investigation, a sample of 80 patients diagnosed with Celiac Disease (CD) was taken, who had followed [...]
