AACC is just around the corner and we have a few more thoughts we would like to share with you.

In our last couple of posts, we explored the diagnostic testing landscape through the lens of the AACC Clinical Expo which will be taking place in conjunction with the Annual Scientific Meeting August 4-8, 2019. To do this, I scraped the AACC website using python and BeatifulSoup to build a list of exhibitors.

 

In this post, I’ll look at the turn over from 2018 to this year. Believe it or not, there are quite a few companies that will not be returning after last year. But there is almost the same number of apparently new companies that will be exhibiting for the first time this year (or who took a break in 2018).

 

So, let’s dig in. Here are the number of companies that exhibited in 2018 and will be exhibiting this year, broken down by those that exhibited only in 2018, in both 2018 and 2019, and only in 2019:

AACC Exhibitors by Year

So, there are 10 more companies that will be exhibiting at the AACC Expo this year than there were in 2018. What does this look like for diagnostic testing companies?

AACC Dx Co Exhibitors by Year 2018-2019

AACC Dx Co Exhibitors by Year 2018-2019

Of the 113 new companies for this year, what subcategories are they focusing on? To find out, I used the pandas and bumpy libraries for python to generate a co-occurrence matrix for a heatmap.

 

It looks pretty much looks like the heatmap for all the diagnostic testing companies (see my previous post), with infectious disease testing, point of care testing, rapid tests, and molecular testing having the most activity:

Co-Occurrence of Dx Testing Subcategories 2019

Co-Occurrence of Dx Testing Subcategories 2019

So, let’s see if there are any words that pop out in the profile descriptions provided by these companies. I used the wordcloud package for python to generate this graphic:

AACC most commonly used words 2019

AACC most commonly used words 2019

Since many of the same words are used by all companies, I had to exclude a pretty large list of words so I could highlight the areas of interest. (The list of excluded words for this analysis had words like “product,” “diagnostic,” “test,” “lab,” etc.)

 

And here are the words that are more prominent from companies that exhibited in 2018 but won’t be exhibiting this year:

AACC most commonly used words in 2018 not in 2019

AACC most commonly used words in 2018 not in 2019

The big difference between these two groups of companies is that the word “kit” was mentioned most frequently, in 27% profiles for those exhibiting at AACC only in 2018. “Kit” was mentioned in only 10% of profiles for new companies exhibiting this year.

 

The most frequently used word for new companies exhibiting this year is “IVD” in 20% of profiles, but it was mentioned in profiles of 11% of companies that exhibited only in 2018. Since wordcloud only gives a qualitative graphic, I used the nltk (Natural Language Tool Kit) library for python to get quantitative results.

 

So let’s look at the companies that exhibited last year & will be exhibiting this year:

 

AACC most commonly used words in 2018 & 2019

AACC most commonly used words in 2018 & 2019

For companies exhibiting both years, “IVD” is mentioned in 79% of company profiles and “kit” is mentioned in 56% of these profiles. This makes sense, as we are looking specifically at diagnostic testing companies. [But maybe this implies that new companies that are exhibiting this year are focusing less on kit development]

 

So, let’s see if there has been any change in the subcategories of diagnostic testing from 2018 to 2019 for companies exhibiting both years:

AACC Change in Dx Cos

AACC Change in Dx Cos

We see the addition of cardiac testing the most, followed by molecular diagnostics, cancer testing and hormones.

 

We hope you find this analysis interesting. What do you think about these observations? And if there are other areas you’d like us to look into with this dataset, please comment.

 

Will you be going to AACC ? Let us know!
