Teiko presents research at AACR IO, showing a 48% cell count drop in blood processed after 72 hours.
We’re excited to present our latest research at the first-ever American Association for Cancer Research in Immuno-oncology (AACR IO), highlighting findings that challenge traditional assumptions about fresh blood processing in cytometry. We’ll be at the conference from February 23rd to 26th, sharing insights from our newest study.
🔬 Introducing the "Fresh-Hour" ⏰🩸
Our research looks to see how delays in processing, measured in hours after blood draw (or “Fresh-Hours”), reflective of processing whole blood live within a 72-hour window of collection like in a clinical trial, impact cytometry results.
Here’s what we discovered:
Blood processed within 5 hours ("Fresh-5") maintained stable immune cell population frequencies.
By 72 hours ("Fresh-72"), there was a 48% percent drop in immune cell counts from t = 0, highlighting the need for new approaches to profile blood by cytometry to ensure the results reflect the true biology of patients.
Come visit us at AACR IO and reach out to set up a meeting—we’d love to connect!
