Worldcare Technologies is developing a device that is based on conventional viral load testing technology, but incorporates automation and element-by-element cost-reduction techniques to achieve minimum cost. We are currently in the research and development stage, validating each individual component of our of our three-step process.
ELECTROMAGNETIC RNA EXTRACTION
We begin the process of quantifying the amount of virus in the body by isolating the genetic material, RNA, from a patient's blood sample. We use a series of reagents and beads, in combination with our novel electromagnetic chip based solution, to automate the extraction process. (testing 2 methods)
After extracting the RNA, the sample is funneled into our low-cost thermocycler that was designed with sustainability in mind. Using easily replaceable parts and a consistent and accurate resistive heating method, we multiply the amount of genetic material present to easily image and quantify the amount of virus.
Our last device component is our low-cost fluorescence quantification imager. The patient sample, along with control standards, is placed into our imager which determines the final viral load. Our limit of detection of 500 copies/mL allows clinicians determine whether patients' antiretroviral therapy regimens are working, and whether a patient needs to switch regimens to avoid contracting AIDS and spreading the disease.
