Understanding your results

Your guide to TruCheck test results

TruCheck is a pioneering multi-cancer early detection test—a test that identifies signals associated with a broad range of cancer types using a single blood sample. In clinical studies, TruCheck was able to detect signals shared by over 70 types of cancer.

Things to remember:

  • TruCheck is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer.

  • The TruCheck tests looks for active cancer and does not predict your future risk for cancer.

  • The TruCheck test can identify over 70 types of cancer but it cannot detect all types of cancer and not all cancers can be detected in the blood.

  • False negative and false positive results do occur.

How to understand your results

There are three possible results:
– Positive for malignancy: Circulating Tumour Cells (CTCs) were detected in the blood sample. The analysis suggests the likely organ of origin and malignancy type.
– Negative for malignancy: CTCs are not detected in the given sample. The chance of
having an active malignancy present in the body is low.
– Indeterminate: CTCs were detected in the given blood sample; however, type of malignancy or organ of origin could not be determined. A recollection of a blood sample is required to determine result (free of charge).

What do TruCheck test results mean?

What does a ‘Negative for malignancy’ result mean?

A ‘Negative for malignancy’ result from the TruCheck test means that, within the accuracy limits of the test, no Circulating Tumor Cells (CTCs) were detected in your blood sample.
This suggests that, at the time of testing, there is likely no active cancer in your body that the test is designed to detect. However, it’s important to note that there are some cancers that TruCheck does not cover. Therefore, a ‘negative’ result doesn’t rule out the presence of those specific cancers.
Continuing with your regular health check-ups and any additional cancer screenings recommended by your healthcare provider remains crucial.

What does a ‘Positive for malignancy’ result mean?

A ‘Positive for malignancy’ result from the TruCheck test means that Circulating Tumor Cells (CTCs), which are often an indication of cancer, were detected in your blood sample. Along with this result, the test also provides an analysis suggesting the likely organ of origin and the type of malignancy. This means that the test tries to predict with high accuracy the specific organ that could be affected by cancer.
However, this is a screening test and not a definitive diagnosis. If you receive a ‘positive’ result, your TruCheck report should be reviewed by your healthcare provider, who can guide you on the next steps, which may include further diagnostic testing.
It’s important to remember that only a healthcare professional can confirm a cancer diagnosis.

How TruCheck works

TruCheck is an advanced non-invasive blood test which provides evidence of an underlying malignancy via a safe, simple and quick blood draw. TruCheck evaluates blood samples to detect ‘Circulating Tumour Cells’ (CTCs), which are cancer cells that escape from the tumour and enter the blood stream. TruCheck enriches these CTCs from the blood sample and confirms their identity via a process called ‘Immunocytochemistry’ (ICC). A positive CTC finding is indicative of the presence of an underlying cancer whereas when CTCs are undetectable, the patient may not have a cancer.

Frequently Asked Questions about the
TruCheck test

The TruCheck test is suggested for use in adults with a higher risk of cancer, typically those aged 50 or above. TruCheck does not detect all types of cancers and should be considered a supplemental tool alongside routine cancer screening tests advised by your healthcare provider. The primary goal of TruCheck is to identify cancer signals and predict their origin within the body. It is not recommended for use in individuals who are pregnant, under the age of 40, or currently undergoing active cancer treatment.

Results must be analysed by a healthcare professional, taking into account the patient’s medical history, clinical signs, and symptoms. A result of “No Cancer Signal Detected” does not definitively exclude the presence of cancer. Likewise, a “Cancer Signal Detected” result necessitates further diagnostic evaluation through established medical procedures (such as imaging) to confirm the presence of cancer.

In cases where further testing does not confirm cancer, this could indicate either the absence of cancer or that the test was unable to detect it, including situations where the cancer is located in a different part of the body. Be aware that false-positive (a cancer signal detected when cancer is not present) and false-negative (a cancer signal not detected when cancer is present) results can occur.
