Yet another "what does this mean"

  1. Hi All,

    I know that there are great acronym websites out there but I can't seem to figure or find this one.

    Here goes:

    "Determine PT/INP prior to initiation of therapy and then daily until maintenance dosage is established."

    What does PT/INP mean. I think that PT means Pain Threshold but what is INP?

    Also what does INR mean here:

    "Lab tests: For maintenance dosage, PT/INR determinations at 1-4-wk intervals depending on patient's response; periodic urinalyses, stool guaiac, and liver function tests. Blood samples should be drawn at 12-18 h after last dose (optimum)."

    Thank you Thank you Thank you

    Are you sure it is PT and INP? If it were PT & INR PT stands for protime.

    Prothrombin time (PT) is a blood test that measures how long it takes blood to clot. A prothrombin time test can be used to screen for bleeding abnormalities. PT is also used to monitor treatment with medication that prevents the formation of blood clots.

    INR is International Normalized Ratio, also pertaining to clotting tests.

    i could have sworn that someone else posted this very exact same question not more than a week or so ago, but i can't find the thread!

    pt/inr is a lab test. it is the prothrombin time/international normalized ratio. in nursing jargon it is also called the pro time. it is drawn on patients receiving coumadin to determine the effectiveness of anticoagulation therapy. here are links to information about these tests:

    "Yes, I copied and pasted directly from my Nursing Drug Guide."

    so what this means is there are typos in reference books. A very useful lesson to have learned, I might add.
