Maintrac® CTC Test

The Maintrac® CTC Count test is a simple blood test which finds every Circulating Tumour Cell present in the blood. CTCs in a 15-20mL sample of patient blood are detected and quantified. Live cells are distinguished from fragmented tumour cells and analysed. CTC-count is an independent prognostic indicator, that is, it gives an indication of the aggressiveness of a patient's cancer at the time of the test. A single CTC count test is intended as a simple baseline 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. Patient information hand-outs for your clinic are available upon request by phoning 1300 282 482.
