Where can we get Warfarin checks done in the south of Tenerife?

[Pat44]

Hello

We are visiting Los Cristianos soon and my husband will need to have his Warfarin Level INR checked. Does anyone know where he can get this done, at the Clinic/Hospital or a Private Doctor. Also what the charge will be.

Is Dr K Whittaker still in Los Crisianos.

Many thanks
