The weather stays humid, which could lead to some fog late tonight as winds go calm. Temperatures will cool to the upper 60's. Thursday looks to be the hottest day of the week. Highs will be near 90, and with the humidity factored in, the heat index hits the middle 90's. We'll be under a mostly sunny sky throughout the day. After another very warm day on Friday, temperatures drop dramatically into the 70's by the weekend.
Prothrombin time chart. See the list below: The reference range for prothrombin time is 9.5-13.5 seconds. The reference range for international normalized ratio (INR) is less than 1.3. However, the normal range is highly variable and dependent on the laboratory performing the test.
PT/PTT are laboratory tests that measure the clotting time (how long it takes blood to clot.). PT/PTT are blood tests and INR is a ratio calculated from the PT. At least a dozen blood proteins, or blood clotting factors, are needed to clot blood and stop bleeding (coagulation).Prothrombin, or factor II, is one of several clotting factors produced by the liver.OW PT/PTT = risk for blood clots/ stroke. The INR stands for International Normalized Ratio. The INR is calculated from the PT and is intended to allow valid comparisons of results regardless of the type of PT reagent used among different laboratories (INR = [patient PT / mean normal PT]).
