- All labs report INR for patients who have reached a stable response to Coumadin therapy
- Therapeutic range 2-3
- INR > 5 = Increased risk of hemorrhage and require immediate attn


ISI - Correct Answer- International Sensitivity Index


Mean Cell Volume (MCV) - Correct Answer- - MCV = (Hct% x 10)/RBC count
(million/mm3)
- Normal values 80-100fL


Mean Cell Hemoglobin (MCH) - Correct Answer- - MCH = (Hgb (g/dL) x 10)/RBC count
- Normal values 26-32pg


Mean Cell Hemoglobin Concentration (MCHC) - Correct Answer- - MCHC = (Hgb (g/dL) x
100)/Hct%
- Normal values 32-36%

R time - Correct Answer- - Clotting time
- Increased = decreased clot formation
- Treat w FFP


K time - Correct Answer- - Clot kinetics
- Increased = deficient fibrinogen
- Treat w cryo


Alpha angle - Correct Answer- - Decreased = deficient in fibrinogen
- Treat w cryo


MA - Correct Answer- - Max amplitude
- Clot strength
- Decreased = deficient in platelets
- Treat w platelets


LY30 - Correct Answer- - Lysis at 30 min
