Statistical Features of Diagnostics surveys the measurements used to assess a diagnostic’s accuracy. Diagnostics must achieve a certain level of accuracy before receiving regulatory approval. Learn the meaning of variability, sensitivity and specificity and how each is calculated. Learn how these measurements are used to determine false negative and false positive percentages. If you are new to diagnostic development and need a primer on the measurements needed to achieve regulatory approval this course is for you.

Suggested Prerequisites

Diagnostic Development & Approval
How Diagnostic Tests Work: DNA-Based Diagnostics
How Diagnostic Tests Work: Protein-Based Diagnostics

  1. Produce and interpret a standard curve to analyze a diagnostic’s test results.
  2. Recognize types of data distributions and how each is used to determine if a patient falls in the normal or abnormal range for a disease.
  3. Choose the correct measurement to determine the disease state of a patient.
  4. Explain how precision, bias, specificity and sensitivity measurements determine the accuracy of a diagnostic.
  5. Discuss how false positive and false negative percentages and their comparison to the “Gold Standard” determine if one receives regulatory approval for a novel diagnostic.

You have two weeks from time of purchase to complete any of the online courses. For example, if you purchase the course at 9 am on Saturday, the course will close at 9 am 14 days later.

You can pay an additional fee for an extension.

Our online courses are between 40 minutes and 85 minutes in length. We suggest allowing 20 minutes to take the end of the course quiz and 10 minutes for the course evaluation. 

Yes, each course has an accompanying pdf that contains all of the presented course information. You will be able to download the pdf once you have registered for the course. 

There are no refunds if you decide to not take the course once you have registered. 

The online courses are fully animated with a professional voice-over. Each course begin with an overview of what you will learn, the course itself, and then ends with a course quiz to assess your understanding.

You can repeat the course as often as you like within your two week run time.

You have two chances to pass the quiz. A passing score is 70% or higher. 

Each course is to be taken by one individual. If you would like to take our online courses as a group, please contact Stacey Hawkins at This email address is being protected from spambots. You need JavaScript enabled to view it. for pricing.

There are three requirements to receive your course certificate. 1. You must view the entire course. 2. You must pass the course quiz with a 70%. 3. You must complete the course evaluation. You can download and print your certificate from your dashboard.

Before moving on to the next section of our on-demand, online courses, all slides within a section must be viewed.

There is an easy way for you to see which slides you have completed and not completed in the course. Look at the menu on the left side of the course- the slides that have been seen are darkened and the slides that have not been seen are light.
