Characteristics of DM
Polyuria, polyphagia, and polydipsia are classic symptoms of this type of DM.
What is type 1?
A glucose level must be lower than this number to be definitive of hypoglycemia.
What is 55 mg/dL?
This is the color tube you should collect for a lactic acid level.
What is grey?
This is how much lower a whole blood glucose measurement will be than the glucose level in the plasma from the same patient.
What is 10-15%?
A HgbA1c% of this level or higher is a criterion for a diagnosis of DM if measured with an NGSP certified method.
What is 6.5%?
What are high levels of hormones that affect glucose metabolism?
This test confirms a diagnosis of gestational diabetes in a pregnant patient.
What is a modified OGTT?
This is the level of lactate you would expect to see in a patient with bacterial meningitis. (High, low, or normal)
What is high?
This is when you should centrifuge a plasma tube for blood glucose measurement to preserve the amount of glucose in the tube.
What is immediately upon receipt to the laboratory?
This is the type of measurement most commonly used in clinical labs for HgbA1c%.
What is an immunoassay?
Insulin resistance is a characteristic of this type of diabetes mellitus.
What is type 2?
A fasting blood glucose level of this value or higher is consistent with diabetes mellitus.
What is 126 mg/dL?
What is tissue hypoxia?
This is the color tube that should be drawn if you cannot separate the cells from the plasma immediately for a glucose measurement.
What is a grey top?
An A1c level below this percentage is indicative of well managed blood glucose levels in a patient with diabetes mellitus.
What is 7%?
Autoimmune destruction of these cells in the pancreas lead to type 1 DM.
What are beta cells?
If a non-pregnant patient had an OGTT with a glucose level of 100 mg/dL in the fasting sample and 190 mg/dL in the 2hr sample, they would have this condition.
What is impaired glucose tolerance?
These are the two reagent system used to measure lactic acid.
What are LDH and lactate oxidase?
DAILY DOUBLE
When using the hexokinase reagent system, the amount of glucose in the patient sample is proportional to the formation of this product.
What is NADPH?
The results from this test reflects the average blood glucose level over the past 2 weeks.
What is fructosamine?
Impaired fasting glucose and impaired glucose tolerance are colloquially referred to by this name.
What is pre-diabetes?
A patient that is suspected to have fasting hypoglycemia should have these three sets of tests ordered.
What are liver function tests, renal function tests, and insulin + C-peptide levels?
This is the main etiology of type B lactic acidosis.
What are conditions that interfere with the conversion of lactic acid to glucose?
This is the second exzyme utilized in the reaction for the glucose oxidase method of glucose measurement.
What is peroxidase?
These 3 conditions invalidate an A1c test.
What are blood transfusions, hemoglobinopathies, and in vivo hemolysis?
