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.

Notes for Providers:

  1. A complete blood count (CBC) with differential is required and will be ordered from IAA Laboratories alongside the SIP and BAT tests.
  2. SIP and BAT tests cannot be ordered together; neither test can be ordered if a SIP or BAT test was performed in the past 6 months.
  3. Courier services can be arranged for clinics in the DC Metropolitan Area. Please contact us for more information.
