An in vitro method for detecting presence of cancer includes obtaining a single hair sample. An x-ray beam is emitted from a source towards the hair sample. A small angle X-ray scattering (SAXS) intensity profile is generated after the x-ray beam hits the hair sample. The SAXS profile is received on a detector to obtain SAXS data, which is desmeared and Kratky Analysis is performed. A relative estimation of peak area under 1.38 nmto 0.89 nmfrom keratin and lipid content in the hair sample is performed to obtain R and is corrected by dividing by D, thickness of the hair. R' is computed using formula: 10&#xd7;R/(D&#x2212;R). The value of R&#x2032; is compared with clinically validated samples. If R&#x2032; value is below 0.7, it indicates the presence of cancer and if it is above 0.8, it indicates absence of cancer.

Non-invasive and remote method to screen cancer

The present invention relates to an in-vitro method of detecting Mtb infection by using SAXS profile of hair sample. The invention is an approach to overcome the problem of non-invasively and cost-effectively yet reliably diagnosing presence of active tuberculosis in the patient. There would be no risk to the sample handlers getting infected from the sample, cross-contamination of samples, low cost and quick turn-around time of diagnosis.
