divide by 2.14
How do you convert from BUN to urea?
mutiply by 2.14
How fo you convert the conventional unit of Creatinine (mg/dL) to umol/L?
Creatinine: 113.12
CF = (10/MW) x 1000
= 88.4
Both Creatinine and Bilirubin have:

T or F
F
Close to Cholesterol
How do you convert Conventional unit for T4 to SI?
T4 = 777
CF = (10/MW) x 1000
=12.9
Which among the following is an Accepted SI unit?
a. g/dL
b. mg/dL
c. g/L
d. mg/L
c
From protein
What is the conversion factor if the protein has a Conventional unit of mg/dL?
0.01
The following proteins are routinely expressed as mg/dL?

d
154 mg/dL urea = _______ mmol/L
25.71mmol/L
Solution
154 x 0.167
4.21iron umol/L = ___________ ug/L
23.52
Solution
4.21 / 0.179
4.12 T4 umol/dL = _________ ng/L
319.38
Solution:
4.12 / 12.9
= 0.319379 x 1000
= 319.38
321 mmole/L Potassium = ___________ mEq/L
321 mmole/L
10 mg/dL calcium = __________ mEq/L
5
Solution:
10 x 0.25 = 2.5 mmol/L (This is Molarity = Moles/L)
Since Normality = Eq/L is given
N = M x V
Valence of Calcium is 2 (Ca2+)
N= 2.5 mmol/L x 2
N = 5
Which of the following is monovalent?
a. Magnesium
b. Calcium
c. Chlorine
d. None of the above
c
2mg/dL transferase = ____ g/dL = _____ g/L
0.002 g/dL
0.02 g/L
Solution:
2mg/dL / 1000mg = 0.002g/dL
0.002 g/dL x 10 dL = 0.02g/L
