Was this test shortly after a COVID vaccination? If so, there have been a small number of cases in local support groups of dramatic increases in PSA when measured soon after a COVID vaccination, which return to expected value a month later.
Otherwise, go back to your GP and get checked for a urine infection (dip test). If present, that must be resolved before a further PSA test.
In any case, ask for a PSA retest in 4-6 weeks. If that rise over a year is genuine and not a temporary effect of an infection or COVID vaccination, then you need to be referred to urology due to the rate of rise in a year.
If the rise is following a COVID vaccination and resolves in 4-6 weeks, please fill out a yellow card on the COVID vaccination: https://coronavirus-yellowcard.mhra.gov.uk/. The "Suspected Reaction" field to use is "PSA increased".
If you are still on Finasteride, you need to remember to double your PSA readings.
