LABS Flashcards
ALT
Enzyme that converts proteins into energy in the liver, is released when cells are destroyed.
Sign of liver damage
Normal 7-56 u/L
AST
Enzyme that converts proteins into energy in the liver, is released when cells are destroyed.
Sign of liver damage
Normal 0-35 u/L
Anion Gap
Differences in ECF anions/cations
Tells you cause of acidosis
Na+ - ( HCO3- + Cl-) = anion gap
Normal is 8-12 = bicarb loss
High > 12 is excess acid
ABG
pH 7.35 - 7.45
PaCO2 35-45
HCO3 22-26
PaO2 80-100
SaO2 > 94%
GFR
How well kidneys are filtering
calculated by BUN/CRE
Normal 90-125ml/hr
Geri 60ml/hr
aPTT & PTT
Clotting time
Normal aPTT 30-40 sec
Normal PTT 60-70 sec
Theraputic 1.5- 2.5x normal range
Creatinine
Constant waste product from muscle use, measures kidney function. Higher serum levels = kidney dysfunction, low = malnutrition or lack of movement
Normal 0.6-1.2
BUN
Waste products
High levels indicate kidney disfunction
Normal 5-20
HbA1c
Test to dx diabetes
percent of glyconated HGB which doesnt breakdown
> 6.5% = diabetes
6.4 - 5.9% = prediabetes
< 5.7% = normal
INR
How long it takes blood to clot
Theraputic 2-3
4-5 in high risk patients
TSH
Troponin
NT-proBNP
CK-MB
BNP
Lactic Acid
CRP
