Leuko: Funding, Investors & Team (Sep 2026)

Leuko Labs has created a non-invasive device for monitoring white blood cells. Assessing white blood cells is crucial in many medical situations, such as managing chemotherapy and detecting serious infections. Currently, this test is invasive and not easily accessible, requiring patients to travel for blood draws and lab tests. With Leuko Labs' PointCheck device, immunosuppressed patients can now undergo more frequent testing, leading to better quality of life and clinical outcomes.

About FundedIQ's Leuko Funding Data

FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.

Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Leuko is left off this page rather than filled in.
