Abstract: A device for testing a biological sample includes a housing, two or more test pads, and a sample pad. The sample pad and test pads are disposed within an interior portion of the housing. The sample pad is in fluid communication with an opening defined in an outer surface of the housing for receiving the biological sample. At least a portion of each test pad is in contact with the sample pad and is configured to test the biological sample. At least one window is defined in the outer surface of the housing adjacent the test pads such that the test pads are visible from outside of the housing. A first test pad may detect a threshold amount of CD44 in the biological sample, and a second test pad may detect total protein in the biological sample. The results are then used for early detection of cancers.

Abstract: A system for testing a biological subject includes an imaging device and an imaging agent detectable by the imaging device, for detecting amount and location of a biomarker in the biological subject. The imaging agent includes a fluorescent microsphere and a targeting member attached to the fluorescent microsphere. A method of testing a biological subject using the system includes providing the imaging agent, applying the imaging agent to a testing location of a patient and imaging the imaging agent in the testing location by the imaging device, so as to detect the amount and locations of the imaging agent. A method of screening and diagnose a cancer that is accessible via cavity of a patient, includes performing a CD44 and total protein test, and if the result is positive, performing an imaging test.

Abstract: A device for testing a biological sample includes a test strip. The test strip includes a substrate having a first surface and an opposite, second surface; a first sample pad and a second sample pad disposed on the first surface and the second surface respectively, and configured to receive the biological sample; a first test pad disposed on the first surface, in contact with the first sample pad, and configured to test the biological sample received from the first sample pad; and a second test pad disposed on the second surface, in contact with the second sample pad, and configured to test the biological sample received from the second sample pad. The first and second sample pads may be configured to evaluate the CD44 protein and total protein of the sample, and used for early detection of neck squamous cell carcinoma (HNSCC).
