1drop Inc.

Global Mobile Healthcare Leader, 1drop



The user can test for biomarkers with a single drop of blood with just a smartphone
and low price biosensors. No need for a special device.


1drop™ products allow the patient
to add new biomarkers just by updating the 1drop™ smartphone application.
We plan to support more over 23 biomarkers for measurement.


Instead of having to learn to operate a complicated medical device, the patient can test for health problems easily and conveniently through a smartphone.
