Hey there,

PLAB is organized by general medical council (GMC) of UK. Students who passed out from university certified by GMC are only eligible to give exam of PLAB.

Sometime some universities are blacklisted by GMC and students of that university can't give exam of PLAB.

So you can mail GMC and ask them about your university and if your university is certified by GMC of UK.  Then you can definitely give exam of PLAB.

Hope this information will be helpful for you.

Good luck!
