Diagnostic sensitivity is the ability of a test to correctly generate positive result for people who actually have the disease.(True Positive rate) e.g. If sensitivity of a test is 90%, it will give positive result for 90% of people who have the disease, but will give negative results (False negative) for 10% people who actually have the disease and should have tested positive. It is calculated as Sensitivity=(True Positive/ Total positive)× 100 Total positive=(True positive+ False Neg)
Diagnostic specificity is the ability of a test to correctly generate negative results for people who actually do not have the disease.(True negative rate). Example- A test with 80% specificity, will give negative results for 80% people who actually do not have the disease.But, it will show positive results (False positive) in 20% of people, who actually do not have the disease and should have tested negative. Specificity=(TN/ Total Negative)×100, Total Negative=True negative+ False positive
Good Morning Mam, We have a new lot qc vial , After that qc runs 20 data points then calculate mean and sd value and set in instrument after that how to activity for NABL and NABH guideline? Please in Hindi Thank you
Hello mam can you take lecture on corrective action and preventive action taken when IQC is out. Also how to rectify the exact type of error and how to correct it using daily IQC graph.

Thank you so much❤
Ma'am can you futher explain diagnostic sensitivity and diagnostic specificity? Didn't get it through the video.

Total Negative=True negative+ False positive
Nice and important
Mam also take a lecture on calibration, standards and QC
