Length can be adjusted from 37.5 to 46.5 inches. The player changes the length using a PING adjustment tool that threads into a locking ring on the shaft. Turning the tool loosens the ring, allowing the shaft to slide telescopically. The player then adjusts the shaft to the desired length.
A PT and INR are ordered on a regular basis when a person is taking the anticoagulant drug warfarin to ensure that the prescription is working properly and that the PT/INR is appropriately prolonged. There is no set frequency for doing the test.
A blood test is needed to determine the effect of warfarin for each person and this is measured as the International Normalised Ratio or INR. The INR is a measure of how long it takes for blood to clot. The INR for a person not taking warfarin is 1. The higher the INR, the longer it takes for blood to clot. The desired INR for you will depend on the reason for which you are taking warfarin. Your doctors will try and keep your INR within a range â called the target INR range.
