Flow Cytometry Testing

The Flow Cytometry Laboratory at Virant Diagnostics is committed to offering patient-focused, informative, and impactful immune testing. We take pride in patient care with a focus on rapid turnaround time, expert interpretation reporting, and customizable testing solutions.

About Our Flow Cytometry Laboratory

The Virant Diagnostics Flow Cytometry Lab offers standard immunophenotyping (SIP) and basophil activation testing (BAT). SIP testing allows in-depth immune system analysis; BAT, accounting for all characteristics of IgE and allergens, is an extremely useful diagnostic modality in the diagnosis, treatment, and monitoring of various allergic conditions.
