Introducing SamaClip: Painless Screening Enters Routine Use at Anubhav

After a long stretch of design, building, and quiet testing, SamaClip is now in routine use at Anubhav Life Care in Barasat. This is a milestone we have been working toward, and it is worth explaining plainly what it is and what it is not.

What SamaClip is

SamaClip is a small finger sensor that plugs into a standard Android phone and screens for several things at once from a single short recording. It uses light passed through the fingertip (four-wavelength photoplethysmography, if you want the technical name) together with a single-lead ECG. From one painless reading of about two minutes, it looks at oxygen saturation, a non-invasive estimate of haemoglobin, a proxy signal for blood-sugar risk, heart rate, and heart rhythm.

Two design choices matter most.

It is battery-free. The whole thing runs off the phone over the USB connection, drawing very little power. There is no internal battery to charge or replace, and no mains supply needed beyond the phone itself. In places where electricity is unreliable, that is the difference between a device that works and one that sits idle.

It is built to be cheap. The component cost of the device is under $7. That is what makes it realistic to put screening into community camps and routine visits at scale, rather than locking it behind expensive equipment.

What it replaces, and what it does not

In one painless test, SamaClip covers ground that would otherwise mean a pulse oximeter, a lab haemoglobin test, a separate blood-sugar pathway, and an ECG. For a first-line screen, that consolidation is the point.

What it is not is a replacement for a diagnosis. SamaClip is a screening tool. It is designed to flag who needs a closer look and route them into Anubhav's proper diagnostic services and referral network. A screen says "look here." The confirmation still comes from accredited testing. We are careful about that line and we will keep being careful about it.

Why now, and what comes next

We have put SamaClip into routine field use so it earns its keep in real conditions, with real patients, not just on a bench. Over the coming months we will be running a formal validation study at our NABL-accredited centre, measuring how well the screen agrees with reference-standard instruments across a representative group of people. We will report what that study finds when it is done — properly, with the numbers, not before.

For now, the headline is simple. A painless, smartphone-powered, multi-parameter screen is no longer a plan. It is in use, in Barasat, today.
