Specimen Submission Conditions
Confirm specimen specifications and shipping conditions
Before submitting a specimen, please follow the collection, storage, and delivery requirements below.
Collection notes
For vacuum blood collection, discard the first 3 mL of blood, then collect at least 5 mL in a second tube for testing.
Storage and shipping
Store at 4°C and ship under refrigerated conditions.
Sample timing
Samples should be collected and delivered to the laboratory within 28 hours.
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.
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 may emerge as tumor cells undergo phenotypic transition. Their migratory and invasive characteristics make them relevant to 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.
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.

Sample Report
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-white blood cells.
CTC: Hoechst, EpCAM, and CD45 images are reviewed together to support circulating tumor cell interpretation.
FAQ
Questions you may want answered before arranging testing
About 5 business days.
Fasting or water restriction is not required. However, if you recently had surgery, please wait at least one month before testing. If you have inflammation or an active infection, such as a cold or bacterial infection, please wait until your symptoms have resolved.
