Vein-Finder-Assisted Serology Test for COVID-19 Diagnosis

In a report published in the Annals of Internal Medicine, a team of US-based immunologists studied more than 100 cases and found that, on average, it takes around five days for symptoms of Covid-19 to develop. As they also found that 97% of all people who get the virus will develop symptoms within 11 days after they were first infected. This makes serologic tests necessary to confirm if someone really harbors the viral disease.  

“Serology tests are blood-based tests that can be used to identify whether people have been exposed to a particular pathogen. Serology-based tests analyze the serum component of the whole blood. The serum includes antibodies to specific components of pathogens, called antigens.

These antigens are recognized by the immune system as foreign and are targeted by an immunological response. These types of tests are often used in viral infections to see if the patient has an immune response to a pathogen of interest, such as influenza. The tests can be used to diagnose infection”  -Center for Health Security http://www.centerforhealthsecurity.org/

Because of the relatively short time of diagnosis and the ability to test for an active immune response against the virus, serology testing for COVID-19 is widely implemented for investigational purposes at hospitals, airports, and whenever there is a need to examine a suspected case.

In order to collect the specimen, serologic tests are based on venous access, which can be a cumbersome task if faced with some medical conditions that make veins ‘invisible’ to the naked eye, such as, obesity, old age, dark skin, etc.

For this reason, SIFVEIN-5.2 detects subcutaneous superficial veins. By infrared light of research of development patent technology. Displaying in situ image on the surface of the skin.

It has a different wavelength; to allow the absorption of light by oxyhemoglobin in surrounding tissues and vessels. After photoelectric conversion and image processing, the information is filtered to display veins on the screen. It is used to find veins at ease.

To sum up, vein finders help and assist health care providers, in which with the real-time visualization of the veins, they facilitate and accelerate phlebotomists’ task and make it a more comfortable and less stressful process for the suspected person.
