Stats
This is the formula for determining the reference range in a population that follows a Gaussian distribution.
What is the mean +-1.96(standard deviation)?
This type of graph is used to visualize repeated measurements of quality control samples.
What is a Levey-Jennings chart?
Sucrose is this type of carbohydrate.
What is a disaccharide?
A spike in blood glucose will also cause a rise in this hormone.
What is insulin?
This is the end product of aerobic glycolysis in the cytoplasm of the cell.
What is pyruvate?
This percentage of values will be more than 3 standard deviations from the mean in a Gaussian distribution.
What is 0.3%?
Quality control samples must be analyzed at least this often in any clinical lab for random access instruments.
What is every 24 hours?
This disaccharide has fructose in its structure.
What is sucrose?
This pathway is used by the liver to maintain blood glucose levels during a fast.
What is gluconeogenesis?
This is the compound that is the start of the glycolytic pathway, the HMP, and the glycogen pathway?
What is glucose-6-phosphate?
This is the formula for calculating a coefficient of variation.
What is (SD/mean) x 100%?
With a properly functioning analytical system, this is how often you would expect to see a QC result more than 2SDs away from the target value.
What is 4.5% of the time?
This disaccharide, which is found in dairy products, is a reducing sugar.
What is lactose?
A secretion of glucagon is stimulated by a drop in this analyte.
What is glucose?
This is the main purpose of the Krebs cycle.
These two stats are measures of imprecision.
What are SD and CV?
Repeated measurement of a control specimen 20-30 times over several days is how this value is determined.
What is a target value?
This is what happens to lactic acid produced by anaerobic glycolysis of the patient's liver is functional.
What is conversion to glucose through gluconeogenesis?
In the fed state, the liver and muscle will make this compound as a form of short term storage of glucose.
What is glycogen?
The gluconeogenic pathway can turn these three types of molecules into glucose.
What are lactate, amino acids, and glycerol?
By definition, about 5% of healthy individuals will have lab results outside of this range.
What is a reference range?
A failure of the 2-2s, 4-1s, or 10x rules would indicate this type of possible change in the an assay.
What is a change in bias?
DAILY DOUBLE
This is how much a glucose level will decrease if a green top or red top tube has been allowed to sit for 3 hours.
What is 15-30%?
This enzyme, present in muscle and liver cells, is activated during a fast to break down glycogen.
What is glycogen phosphorylase?
These are two important products from the hexose monophosphate pathway.
What are NADPH and ribose-5-phosphate?
