Through the combination of histology guided mass spectrometry (HGMS) profiling and machine learning algorithms, we are able to evaluate the proteomic contents of targeted cells and develop a spectral fingerprint for disease diagnosis and treatment response. Our test results aid veterinarians in better diagnosing a pet’s condition and predicting whether a pet is likely to respond to a particular treatment.
