What causes high protime levels when you are on coumadin?

Your "ProTime" is actually the prothombinase time, or time to coagulation. Coagulation cascade is a complex interaction of chemicals but to put it shortly prothombinase is the first step in forming a clot. Coumadin (warafin) has the effect of preventing prothombin formation (once again this is simplified but meant to be easily understood) prothombin forms thrombin whick allows clotting. Without prothombin there is no/less clotting. The reason your PTT (prothombin time) is monitored is to keep it in a narrow theraputic range not too fast not too slow. Elevated PTT is good, too high and hemmorhage is a risk. Your dietary consumption of Vit K will counteract warafin's effectivness, so changes in diet can throw off your PTT. Maintaining the same Vit K intake will help clinicians keep you warafin dose in the theraputic range.

If the hair is damaged so much that it starts to break, then it might affect the test... but damage on that level will also be easily identified in the test, and likely when collecting, and they can use hair from other parts of the body instead. The best way to beat a drug test, as always, is to avoid drugs.

What blood test can't you draw from a picc line?

IF the pic line has been flushed with heparin , then the coagualtion studies cannot be drawn for the line. Heparin interfers with the APTT test. It will be extremely high or not even read on the analyzer. Also if there are nutrients going into the line and sodium, potassium, it is advisable not to use the pic line. Even if the is 10 cc of blood pulled first to "waste" there is the chance of residual elements in the line itself which will cause fale positive electolyte results as well as glucose and total protein, albumin. If the patient has veins that could be drawn from , it would be much better to get a true laboratory analysis.
