Carbs Flashcards
What tube is recommended for glucose testing and why?
Sodium fluoride slows glycolysis
Fasting reference for glucose
What are arterial and capillary values?
Normal CSF values
70-99 mg/dl
2-3 higher
Two thirds of plasma levels
Name the hormones that regulate glucose levels. What is there action and source? What acrynom use to remember those that increase serum glucose?
Pg 102 notes
Explain the 3 stages: normal, diabetes mellitus, pre diabetes. FFG, OGTT, Hgb A1C values.
Pg 103 top table
Explain how oral glucose tolerance test works? Standard dosage, children, pregnancy
Used to diagnose diabetes. 75g, 1.75-75, 50g
Given drink, measure sample 2 hours after if greater or equal to 140 then give larger dose and compare the testing results
What are the 4 tests for monitoring diabetes and how do they work.
Pg 103
How to calculate eAG
A1C of 6 percent is an eAG of 126. For every 1 percent increase in A1C
What are the test methods for glucose urine and serum/plasma glucose?
Glucose oxidase and hexokinase (nadp to nadph)
What are other carb tests? How do the tests work?
Lactose tolerance
Xylose absorption
Lactic acid
What are the 4 types of lipids
Tryglycerides
Cholesterol
Phospholipids
Fatty acids
What are lipoproteins and name them and there function?
104 and 105
What are the requirements for lipid specimen collection and handling?
12 hour fast
Turbid due to chylomicrons or increase triglycerides which indicates a non fasted sample
Test method for HDL direct vs indirect?
LDL test method
Measures HDLe without treatment and indirect removes other lipoproteins by precipitation
Does not use pretreatment direct
Friedewald method calculating ldl and vldl
LDL = tc - HDL - tg/5
Vldl = tg/5
Positive risk factors for cardiac
Negative risk factors
