There's no one agreed set of PSA thresholds.
NICE gives:
Below 40 Use clinical judgement
40 to 49 More than 2.5
50 to 59 More than 3.5
60 to 69 More than 4.5
70 to 79 More than 6.5
Above 79 Use clinical judgement
ICBs, Cancer Alliances, and individual hospital urology departments can override these on regional and local basis.
Urologists sometimes use the BAUS recommendations:
40-49 2.7
50-59 3.9
60-69 5.0
70-79 7.2
80-84 10
85+ 20
Borderline results should be retested in 3 months before referral.
CHAPS uses the following thresholds, which have been worked out by Chris Booth from his research into screening using PSA testing, and are roughly between NICE and BAUS levels:
Under 50: 2-3 retest in 3 months and refer if >2. Refer immediately if >3.
50-59: 3-4 retest in 3 months and refer if >3 Refer immediately if >4.
60-69: 4-5 retest in 3 months and refer if >4. Refer immediately if >5.
Over 69: 5-6 retest in 3 months and refer if >5. Refer immediately if >6.
CHAPS also recommends retest intervals depending on the last test result.
The NICE and BAUS figures are specified as for men with symptoms (pretty meaningless given current research shows most men diagnosed have no symptoms). The CHAPS figures are for screening men, and hence for men without symptoms.
