The family waits for hours.
They give up and go home.

CSF cellular analysis is critical for diagnosing neurological disease — but requires lengthy lab processing today. No bedside tool can analyze CSF cells in real time.

After lumbar puncture: fix → stain → cytospin → load Neubauer chamber → manual microscopy to identify cell populations. Every sample. At high volume in CROs.
Load raw CSF directly onto the chip. Get labeled cell populations in minutes. Zero post-collection prep. Major CRO collaboration in early planning to validate equivalency.
Studying bloodborne parasite mechanism of action — and tracking routine parasitemia in culture — still requires Giemsa staining and manual microscopy, even at well-funded pharma labs.
Real-time parasitemia counts and morphology assessment — no fixation, staining, or manual microscopy. Two planned studies with a major pharma company: drug mechanism of action (in vitro) and a sickle cell disease clinical trial in Uganda.
Live/dead, immune cell activation, CAR-T screening, iPSC differentiation — many use flow cytometers that require weeks of antibody panel development, costly reagent lots with variability, and dedicated trained operators.
Label-free morphology-based readout replaces the staining step entirely. Load a chip — any lab member can run it. No antibody panels. No reagent costs. No specialist required.
Across all three: AI-powered label-free imaging cytometry eliminates all sample prep.
No fixation. No staining. No reagent lot variability. No waiting. Load a chip — results in real time.
