From what I have come to understand, siliva testing is not an accurate method for testosterone levels. The gold standard is still from a blood draw. As for measurements, when someone is claiming to have, say for instance "1200" for their test levels, they are talking about ng/dl. Your test was pg/ml. 1 picogram / ml = 0.1 nanograms / dl. Just a different unit of measurement. Most labs will only measure up to 1500ng/dl. So if your levels are above that, they will come back as +1500

You can get private blood work done online as well. All you need to do is go to your local lab, like Quest to have the script filled. Easy to do, pretty cost effective and you can do them without getting your insurance or your primary MD involved, if that is an issue
