Aliquot has a unique feature when creating a test that allows you to see the history of previous test comments and results. This allows you to compare the current test results with the previous.
From the Main dashboard or anywhere within Aliquot you start by clicking on New Report button.
After clicking on new report, you will come to the Create report screen. You will need to fill out the filter on the left, choose a template and create a report title.
Next scroll down and click the create report.
You will then be on the report page. You will find the component you want comment history on and click the blue arrow to the right of the component. A new menu will appear and you will see a previous comment button on the left.
Finally, after clicking the arrow you will see the blue menu with comments and results. Clicking previous comment button will bring up the history of previous test with comments and even images.
