Preclarus® Investigator Site Portal

With the Preclarus investigator site portal and its
companion mobile app, you may never lose a specimen again.

The Preclarus® investigator site portal was designed to make it easier for sites to manage their PPD Laboratories central lab clinical trials with online tools for subject registration, sample management and receiving test results.

Now, with the companion mobile app, managing trials and patients is even easier. The mobile app delivers all the features of the desktop version to mobile devices so that busy investigators have real-time test results and study tools at their fingertips 24/7.

One of the most exciting features of the Preclarus investigator site portal is the electronic lab requisition. This new tool allows sites to log previously bar-coded samples into the portal before they leave the office. Once the connection has been made between the sample/patient information and bar code, the data are immediately available to PPD Laboratories. The electronic requisition strengthens the chain of custody by giving sites and PPD Laboratories full visibility to all samples in real time.

The Preclarus investigator site portal also simplifies and streamlines sample shipping. The sample management tool keeps track of samples, helps sites organize shipments according to shipping conditions and provides reminders when samples are waiting to be shipped.
