Our Research Project includes efforts to develop a very low cost, rapid, battery powered, mobile, fully automated nucleic acid amplification testing (NAAT) system that auto charges itself in the field with photo voltaic cells. These kinds of devices have growing importance to many applications, including biomedical POC, (point of care) testing for remote villages, and military operations. We propose PCR for limited resource settings for it’s superior specificity and ultra-sensitivity. Cancer tests must be specific to the marker they or looking for, if the test is not specific, this could result in a false positive. The results could suggest that a tumor is present or growing when it’s not despite treatment. Also, the cancer test must be sensitive to the tumor marker it is looking for. If the test is not sensitive enough, the results might suggest a false negative. This is when testing shows that a person does not have a tumor when they actually do. PCR testing is the most specific and sensitive testing that can be done.
