| Answer |

|
| PT - Prothrombin Time |
11-12.5 seconds (monitors coumadin therapy) |
| INR |
2.0 - 3.5 |
| PTT - Partial Thromboplastin Time |
60-70 seconds (commonly used to evaluate Heparin therapy)(Think H=TT they both have two lateral lines the H of Heparin and the TT of PTT)(So PT monitors Coumdin, and PTT monitors Heparin) |
| APTT-Activated Partial Thromboplastin Time |
30-40 seconds (this is the PTT test with activators added to shorten shorten normal clotting time and provide a narrow normal range)(jsut think it is faster so it is about half the time as PTT) |
| Bleeding Time |
1-9 minutes (frequently performed on preop patients) (evaluates platelet function and vascular constiction capability) |
| Platelet count |
150,000-400,000 (remember this is a high number, we want to have this large number of platelets so our blood clots appropriately when we get a cut or scrape) |
