I went in to the doc for my 2 yr post davinci surgical checkup.
Doc says things are fine..........

one thing concerned me, two previous (6 months and 12 month) PSA values were < 0.06
Mondays PSA reading was 0.1 ...........

Doc indicates that they are one and the same, and that its "zero". I have used the same lab every time, if you were me, would you accept that as a zero, or raise an eyebrow that it is no longer < 0.06 ?

    Low Detection Limits of Assays

    Laboratories use several types of assays which can vary in results, depending in their detection limits. The ultra sensitive with readings on the two decimal places (0.XX ng/ml) were used in your 6 and 12 month tests. This time the assay's low detection limit may have been for one decimal place (0.X ng/ml).
    If the above is correct than your doctor’s assertion is valid. Any number below 0.1 (ex; <0.06) is considered 0.1.
    You can repeat the test and request for the ultra sensitive, just for peace of mind.

    I hope for your continuous path in the Zeros World.

    The best to you.

    First conrats on your 2 year
    First conrats on your 2 year anniversary! I would keep track of your result for comparision on your next test. Many men go by the ultra sensitive test since it can more accurately show a doubling time. However my Doctor uses the single digit test. I've asked my Doctor about this and he has told me that in his opinion that men tend to worry to much with the ultra sensitive test.

    If you hit the .2 number then your doctor may incourage taking further action. Best wishes as you continue your journey.

    THanks,
    Yes, the doctor
    THanks,

    Yes, the doctor indicated that >0.2 is an issue when I questioned him, in fact he said that not long ago, they used 0.4 as the time to radiate criteria.

    I just was curious, I deal with numbers (at work) alot, so I was doing the math.... :-)

    congrats. The number is fine if the next one moves then be concerned. I had my surgery less than 5 weeks ago. I go for my first post op PSA tomorrow. Nervous a little.
