    Weird Ways to Remember Lab Values

    Hey guys,

    I hope you find these helpful. These are some weird ways to help you memorize some important lab values. The keyword is weird.

    Partial Thromboplastin Time (PTT)

    • PTT measures how long the blood takes to clot (increased #=increase bleeding time)
    • In PTT the TT looks like a H—so we use PTT as our test when using Heparin.
    • Think Harry Potter—Heparin Protamine (sulfate) to remember the antidote.
    • PTT normally ranges from 30-40 seconds
    • Proper Teaching Time is 30 to 40 years old—this is how old your teachers are.

    Prothrombin Time (PT)

    • PT also measures clotting times
    • Pills TakIN Regularly –PT and INR go together
    • INR—I=normal is 1, but therapeutic ranges from 2 (NR, 2 letters after the I) to 3 (INR, 3 letters in total)
    • Usually measured when on Coumadin / Warfarin
    • Think Wiz Khalifa—Warfarin (vitamin) K to remember the antidote.
    • PT normally ranges from 10-15 seconds
    • Pre-Teens are 10 to 15 years old—you hit the double digits but still cant drive
