Need to buy one for my mum.

I saw there are Smart Watch claimed that can measure Uric Acid.

Anyone tried it before? Accurate?

i think there is uric acid test kit like blood glucose test kit.

Yes, but those are invasive (means need to take some blood sample) test.

But my mum doesn't know how to use it correctly.

i never heard of this, probably in RnD. even the monitoring currently available at market wont be as acccurate as la, can use for monitoring only.

As

i think its still not available in the market yet
