The TBIA screening test is a highly accurate method to detect breast and colorectal cancer at a very early stage. Through the spectroscopic analysis of a simple blood sample, the TBIA tecnique observes the body’s own immune system response to tumour presence. Being able to observe such early biochemistry changes in the blood sample, the TBIA method detects cancer at stage 0 with great sensitivity (>90%) and specificity (>80%), resulting about 15% more accurate than screening methods currently in practice, such as mammography and colonoscopy. Further, the TBIA test is extremely cost-effective, costing about €100 per test to the end user – 4 times cheaper to perform than a mammography and approximately 8 times cheaper than a colonoscopy. The test does not require the same high level of infrastructure as mammography or colonosocpy, and can be easily performed everywhere by a nurse, without the supervision of highly skilled technicians. The TBIA score, the result of the test, is electronically mailed to the lab or physician, and is very easy to interpret. This makes TBIA the most suitable screening test where the high MU and personelle costs limit the availability of extensive cancer screening programmes.
