5,000–10,000 mm3

Question 12

ESR (erythrocyte sedimentation rate)

Answer 12

less than 20mm/hr is normal

Question 13

Blood lipid levels

Total serum cholesterol
LDL
HDL
Triglyerides

Answer 13

Total: less than 200mg/dl is desirable (if pt. has increased risk, less than 150)

LDL (lethal): less than 130 mg/dl

HDL (healthy): males greater than 45 mg/dl
females greater than 55mg/dl

triglycerides: less than 150 mg/dL; males 40–160;

Question 14

Anticoagulant Therapy coag times

PT
aPTT
PTT
INR

Answer 14

PT: 11-12.5 seconds. Therapeutic range with therapy is 1.5–2x normal. critical value is greater than 20 seconds
(Pysical Therapy requires 11-12.5 reps and 1.5-2 sets. I can never do 20 reps though)

aPTT: 30–40 seconds. Critical value is greater than 70 seconds. 1.5-2x the normal is the therapeutic range on heparin. (A PresenTaTion on heparin should have 30-40 slides, but never 70; our goal is 1.5-2 presentations a day)

PTT: 60–70 seconds. Therapeutic range with therapy is 1.5–2x the normal. Critical is greater than 100
(my Personal Track Trainer charges 60-70 dollars, for 1.5-2 hours a week, but he never charges more than a 100. )

INR: 0.8–1.1. Therapeutic range with therapy is 2–3. Critical value is greater than 5
WAR from 2008–2011, was good for absolutely nothing, I know right?. 2-3 people survived, but not 5.

total protein: 6–8g/dl

AABP–the liver is behind your abs (AABPs)
