I think that any reading less than 0.1 is essentially zero.

Hi mailman,- You have nothing to worry about from readings .03 ng/ml. These reflect readings performed with a Hyper-Sensitive assay material which is considered reliably sensitive to the hundredths of a Nanogram (which itself represents 1 Billionth of a Gram).

The long-standing Clinical definition of "undetectable" PSA is anything LESS THAN 1/10th of (<0.1 ng/ml) of a Nanogram. Your 0.03 ng/ml is SUBSTANTIALLY below this traditional Standard.

Although you indicate that your previous PSA readings have been "0", I suspect this is probably not true if the Hyper-sensitive assay has been used in the past. More likely, your previous PSA readings were done with the Standard PSA assay which would have been reported as LESS THAN 0.1 ng/ml, its stated reliability level (<0.1).

In casual verbal communication, medical personnel often cite such results as 0, since they actually reflect an "unmeasurable" result, or "undetectable".

At any rate, it is nothing to be concerned about as long as monitoring PSA tests continue to be reported at any level LESS THAN 0.1 ng/ml (anything from 0.000 thru .09 ng/ml). Congratulations! - John@newPCa,org (aka) az4peaks
