What we do

We at PZM Diagnostics LLC, are testing the blood from potential Crohn’s patients for the presence of MAP by three separate methods: blood culture, serology and molecular identification. We will first culture for MAP. We will test the blood antibody titer against MAP from the patient’s plasma, and we will analyze the patient’s blood by molecular methods for MAP.
