Questions about this test
Is TPA a screening test for cancer?
No, TPA is not used to screen healthy people. It may be used alongside other tests to follow some known cancers.
What else can raise TPA?
Inflammation, infections, and liver or kidney problems can raise it. That is why a single result is not enough for a diagnosis.
Why is TPA rarely ordered?
Many more specific cancer markers are now available. Ask the hospital and your doctor why this one has been chosen for you.
