The use of surface‐enhanced Raman spectroscopy (SERS) to determine spectral markers for the diagnosis of heparin‐induced thrombocytopenia (HIT), a difficult‐to‐diagnose immune‐related complication that often leads to limb ischemia and thromboembolism, is proposed. The ability to produce distinct molecular signatures without the addition of labels enables unbiased inquiry and makes SERS an attractive complementary diagnostic tool. A capillary‐tube‐derived SERS platform offers ultrasensitive, label‐free measurement as well as efficient handling of blood serum samples. This shows excellent reproducibility, long‐term stability and provides an alternative diagnostic rubric for the determination of HIT by leveraging machine‐learning‐based classification of the spectroscopic data. We envision that a portable Raman instrument could be combined with the capillary‐tube‐based SERS analytical tool for diagnosis of HIT in the clinical laboratory, without perturbing the existing diagnostic workflow.
