To combat the COVID-19 pandemic many people have been using a pregnancy test also known as a polymerase chain reaction (PCR) test. Typically the pattern of DNA and RNA that the test produces is the same as the diagnostic test so you would easily identify a healthy person. However the molecular patterns involved in human pregnancy are not the same and handling the PCR test with children is expensive and labor-intensive. Now a team of scientists at Tsinghua University Taiwan has shown that it is possible to find antibodies to a virus found in macrophages by examining the blood of very ill patients.
The team warned that the test is only suitable for very-ill patients and it could not be used in intensive care units or in patients who are very sick in person as it would require too much DNA to read. The team is also at risk of spreading HIV and its cousin hepatitis A. It will contribute to the global effort in developing testing for HIV and other viruses. The group brought the conclusion about using PCR testing in the laboratory. The report has appeared in the journal Science Translational Medicine.
The first risk to blood of patients infected with the virus is that any infected blood cells without reason deposits antibodies in the joint (biological syndrome). There is little chance of diagnosis and possible complications to families infected.
