What is the definition or description of: psa, total with reflex to psa, free?

PSA: "prostate specific antigen" is a blood test to evaluate for prostate cancer. Psa comes essentially only from the prostate. It tends to increase with age, size of prostate and in prostate cancer. Free psa is only tested with total psa is between 4 and 10 ng/dl. A free psa that is low (<10) is concerning for cancer, when high (>25) is reassuring, and is not very helpful when between 10-25%. ...Read more

Psa is a protein made in the prostate gland that functions to liquefy sperm. It is a serine protease made by both normal and malignant prostate glands.

PSA at 7.65 is this high after protate removal hello remember free ?

PSA  at 7.65 is this high  after protate removal
hello  remember free
?

That's high.: If you've had your prostate removed, then the PSA should technically be zero. So any elevation would be concerning. This would need to be investigated right away. Why was it removed in the first place? If it was removed for cancer, then this becomes particularly worrisome. ...Read more

I am 49, psa=0.7 free psa=0.4 in altra sound it says heperechoic mass 11 mmvolume 18 cc hetrogen, is it dangrouse?

Okay, but...?: All the reported findings are in your favor, but i could not deduce why t/f psa was done because it's originally designed for men with psa between 4-10 ng/ml, and usually recommended for men with psa elevation with no cancer found from p-bx so to minimize further p-bx. As to US use, i was not sure if it was indicated. More on psa/p-ca? To <a href="http://www.Formefirst.Com/freeinfoprostate.Html" ...Read more

Md said not to worry about low (7.5) free psa. Is this true or should I see a urologist? 60yrs. Normal psa for age.

Md said not to worry about low (7.5) free psa. Is this true or should I see a urologist? 60yrs. Normal psa for age.

This : This really depends on what your total psa is. If your total psa is between 4 and 10 it is more significant as the lower your free psa, the higher the likelihood of prostate cancer. If your psa is less than 4, the free psa is really not that important. ...Read more

Dear Doctors I am 43 y.o, 3 years ago my PSA was 4.8 and now it is 6.7, with a free PSA ratio of 4, How concerned should I be of Prostrate Cancer?

Dear Doctors

I am 43 y.o, 3 years ago my PSA was 4.8 and now it is 6.7, with a free PSA ratio of 4, How concerned should I be of Prostrate Cancer?

Needs evaluation: For a man of 43, the PSA level is very elevated. Have you had a digital rectal exam? Any family history of prostate cancer? Sometimes inflammatory issues involving the prostate (prostatitis) or urinary tract infections may cause an elevation in the PSA. However, you need to get evaluated by a urologist to ensure that the cause is not cancerous in origin. A set of biopsies may be needed. ...Read more

For 6 I've had prostate issues even had biopsy at 39 PSA was 3.9 test was neg. The last two years PSA .7 with free PSA 26%. Still symptomatic some days worse than others. Worried Drs missed cancer.

Falling PSA is good: Previously elevated PSA was likely due to inflammation, infection or manipulation. Your PSA is now within normal limits and biopsy was negative. All is OK & suggest you stop worrying. There is plenty of real stuff going on round the world to worry about, but, fortunately not your prostate. ...Read more
