Waived test are simple and easy test which can be performed in the home set up.lt has very low incidence and risk for inaccurate results.It is approved by the FDA in Clinical Laboratory Improvement Amendment .It is because of easy portability,space saver and interpretation of report is immediate which is ultimately helpful in right time interventions
Some other example of waived test are
Urine pregnancy test,ESR test,Heamoglobin test,Urine dip stick test

A physician would like to know the mean fasting blood
glucose value (milligrams per
100 ml) of patients seen in a diabetes clinic over the past 10
years. Determine the number
of records the physician should examine in order to obtain a 90%
confidence interval for
µ if the desired width of the interval is 6 units (SE = 3) and a
pilot sample yields a
variance of 60. Show all work or no credit will be

Approximately 9% of the US population has type 2 diabetes. A fasting blood glucose test is one option to test for type 2 diabetes. Using this test, the probability that a person tests positive, given that they have diabetes is 0.6. What is the value of the intersect of diabetes and test result positive? P(diabetes ∩ testpositive) =

A patients fasting blood glucose is high > 300 mg/dL and his serum sodium is falsely low. This could be related to the osmotically active glucose draws water from cells into intravascular space creating a dilution. What would you recommend: to increase his sodium intake or to control his blood glucose?

The most commonly used screening test for detection of Diabetes Mellitus is Fasting Blood Glucose (FBG) test. However, like almost all screening tests, this test is not 100% accurate. In order to evaluate the FBG test carried out by a specific device: 'OneTouch Ultra 2' meter, a more rigorous test is used (a gold standard), which is the Glucose tolerance test. The Table below summarizes the data collected from the study to evaluate the FBG screening test. Please, calculate all...
