With a 93 composite, I think you're just fine. I'm obviously not on an admissions committee and I'm simply giving my opinion but....
I would not retake the PCAT if my composite score was high AND I didn't score lower than 50 in any particular section.
An exception to this might be if English is your second language and you scored lower in verbal; I think schools take that into consideration but who knows.
I got an 86 percentile last year and my lowest section was a 64 in quantitative. I was accepted this year (reapplicant) but not due to retaking the PCAT (haven't received scores yet anyway so that 2nd time was sorta pointless).
Good luck and just start preparing for some interviews!
