Dr Lieberman provided a response, which I have provided for you here:
As with all tests, there are false-positives and false-negatives, and the diagnosis of contact allergy remains a clinical diagnosis in which tests are used to add additional evidence of its existence to a specific agent. The patients completed a special questionnaire aimed at information regarding change of health status from their last visit and determining whether the results of the initial MELISA test and recommendations based on it were beneficial for patients or not. "Titanium: a review on exposure, release, penetration, allergy, epidemiology, and clinical reactivity."

The abdominal pain is associated with titanium allergy reaction from previously inserted titanium-based surgical clips. She had to be hospitalized with strict isolation to wait for her medication regimen to work along with the infusion of IV fluids. RFB should be included in the differential diagnoses when the patient presents with acute reactions after surgical procedures. Some physicians might also recommend in vitro blood tests to detect metal allergy, including the lymphocyte transformation test, the lymphocyte migration inhibition test, and the commercially available MELISA test. How lymphocyte-mediated metal sensitivity affects orthopaedic implant performance remains poorly understood. More information about the metals commonly contained in stents can be foundHERE. The patient initially presented to the clinic with an intermittent right upper quadrant (RUQ) pain in 2016.
