Question: I'm 70 years old and just had my PSA tested @7.5. Should I get the 'free PSA' test to further define what my problem is? How long should I wait to test with the regular PSA test, again?
Answer: Yes, you must do Free PSA test because we use it to calculate the Free/Total PSA Ratio which clearly help in diagnosis of prostate cancer and the need of taking biopsy.
Your PSA 7.5 is exceeded the upper normal limit (4.0), therefore the need for FTPSA Ratio is very much.
Hope that helped you, for more information please lemme know.
