Maintrac® Customised Chemosensitivity Test

Some CTCs can hide in the blood stream for months or years before activating and forming a second tumour. Some CTCs may even resist treatment. This analyses how a person’s CTCs respond when exposed to a recommended chemotherapy regimen or botanical treatment. CTCs that die or survive exposure are said to be ‘sensitiveor resistant’ to the tested treatment, respectively.

Recommended therapies can now be tested. Each test is customised specifically for each patient by the requesting practitioner.

Test for Treatments can be used to:

  • Analyse if a person’s CTCs are sensitive or resistant to a recommended treatment
  • Assist practitioners in deciding on a treatment plan
  • Increase confidence in the therapys ability to reduce cancer spread effectively

This test can only be ordered in addition to a CTC Count. The best way to monitor cancer activity and long-term effectiveness of treatment is via a single CTC count test every 3-6 months.
