  • Course Run Time: 40 minutes
  • Course Level: Level 2 - General
  • Completion Period: 2 week

How Diagnostics Work: Protein-Based Diagnostics focuses on antibodies: what they are, where they come from and how they work. Various antibody-based diagnostics, such as sandwich and bead immunoassays, multiplexed assays, lateral flow assays and chromatography, are explained in detail. Develop an understanding of these diverse tools and how to interpret results, knowledge which can be applied in research, drug development, and patient care.

Section 1: Defining Protein-Based Diagnostics
Introduces protein-based diagnostics by explaining the importance of biomarkers in diagnostics. A biomarker is a measurable molecule indicative of disease.
Section 2: Antibody Technology
Explains the importance of antibody structure and how that structure contributes to its function. Antibody structure and function are exploited by the...More
Section 3: Enzyme-Linked Immunosorbent Assays (ELISA) Technology
Demonstrates the technology and how to interpret results of the widely-used screening test known as an ELISA.
Section 4: Bead Immunoassay Technology
Extends your ELISA knowledge by showing how ELISA technology can be adapted into more high throughput techniques, such as multiplexed bead assays.
Section 5: Lateral Flow Assay Technology
Explains how lateral flow immunochromatographic assay works, its applications and how to interpret its results.
Section 6: Chromatography Technology
Describes the applications of column chromatography in diagnostics and how to interpret its results.

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.
