How long is a UK TB test certificate valid?
6 months, counted from the date of your x-ray.
The date it runs from is the part that catches people out: GOV.UK measures the six months from the x-ray, not from the day the certificate is issued or received. This is the only document on the Skilled Worker list for which GOV.UK publishes a validity period.
“If your test shows that you do not have TB, you'll be given a certificate which is valid for 6 months from the date of your x-ray.”
