Blood Drug Testing

Third try for this question. Why do I need to repeat my prostate blood test?

I just had a physical, including blood work. They told me I need to go back to retake my PSA test. Why? And do I need to fast again for 12 hours?

1. Not sure but perhaps they weren't sure of the results.
2. Greg, I have been diagnosed with prostate cancer and treated for it. The test you are referring to is a PSA which is useful in calling for further investigation of the possibility of cancer. It is not the end all as far as tests go but mine was repeated several times to get consistent readings. I believe I did have to fast before each. If the PSA results indicate a suspicious number, then in my case a biopsy was done to confirm the diagnosis of cancer. The biopsy was uncomfortable, a tad embarrassing but otherwise not excessively painful - I felt a little pin prick or "pinch" as the doc took three or four samples. In your case, maybe they just screwed up the PSA portion of your exam and need to do it over. They can't get accurate readings without the fasting. It's important Greg, so go get it over with and best wishes for a "no sign of cancer" result.
3. They either messed up and didn't get a good reading, or else they did get a reading which wasn't so good, so GET it again! The doc ought to tell you why you need it again! Good Luck!
4. We all make the mistake of not asking questions and then it drives us insane. Call them back and ask why the test needs to be repeated. It just may that the blood coagulated or was not properly handled. If that is the case they need to repeat the test. If they got an abnormal they may want to repeat it to be sure if you are without any symptoms that would elevate it. If it was elevated then ask how high it was. Worst case scenario for a high PSA is prostate cancer (which is treatable in early stages) and it can be something very simple that can be treated with antibiotics. I have never heard that you need to fast but if they are telling you too then do it. Also ask for a copy of the reports. That is your right. Try to stay calm until the retest. Good Luck! Remember ask questions because you have a right to know.
