The mean value of fasting blood sugar among 50 healthy volunteers in a community was found to be 90 mg/dL using a new diagnostic test. In the same volunteers, the gold standard test found a mean of 88 mg/dL. What can be said about the new diagnostic test?

Mean value of fasting blood sugar using gold standard and new diagnostic test
Explanation:
- A new diagnostic test gave the mean value of fasting blood sugar as 90mg/dL when 50 volunteers were taken . This was in comparison with gold standard test which gave a mean value of 88mg/dL for the same number of volunteers.
- Therefore , new diagnostic probably shows a raised blood sugar level which gives a slightly higher mean value because during fasting the body uses its own stored glucose from the liver . It can only have come from your own body (liver). So, it’s a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy. If these levels are sufficiently high ( more than 100mg/dL in an individual) , it would mean insulin resistance or diabetic condition .
- Normally 80-100mg/dL is the normal range . Therefore , in this case , it would mean that most individuals fall under normal fasting glucose value.
- However, when compared to gold standard test , this value is slightly higher . Gold standard test enables high level procedures that are required to establish a particular condition underlying any disease.
- A higher mean value in the new diagnostic test could also mean an error in diagnosis or in calculation of mean value, since gold standard values are considered to be more accurate.
