Report Delivery

What will you receive after testing?

After testing, the report includes the result summary, cell images, and phenotype interpretation information for follow-up reference and discussion.

Reports are typically delivered within 5 business days and focus on the result summary, cell images, and interpretation details needed for review.

If prior test records are available, they can also be organized into a comparison reference to support follow-up review and discussion.

Partial Report Example

Partial example of a CTC testing report, including cell images and interpretation details

Hoechst: Nucleus imaging helps identify the location and morphology of cell nuclei.

EpCAM: Tumor-cell surface antigen imaging supports identification of cells with epithelial characteristics.

CD45: White-blood-cell surface antigen imaging helps distinguish white blood cells from non-blood cells.

CTC: The overlap of Hoechst, EpCAM, and CD45 signals is used as the basis for circulating tumor cell interpretation.

Interpretation Method

Why review both epithelial and mesenchymal CTCs

CTCs shed from the primary tumor may appear in different phenotypes as they circulate in the bloodstream. Reviewing both phenotypes is therefore an essential part of interpretation.

Phenotype review

Epithelial and mesenchymal CTCs are both important for interpretation

Epithelial CTCs originate from cells shed by the primary tumor into the bloodstream and are one of the key observation types in circulating tumor cell testing.

Mesenchymal CTCs arise through phenotype transition and are associated with stronger migration and invasion potential, making them important for interpretation and follow-up.

Epithelial CTCs
Cells shed from the primary tumor into the bloodstream remain an important observation target during testing.
Mesenchymal CTCs
These cells have stronger migration and invasion potential and provide important phenotype information for follow-up review.
