Summary
Brief summary (as posted)
The investigators have developed an assay that can sensitively and specifically detect DNA mutations circulating in human plasma that may be indicators of the presence of a solid tumor. This study is a pilot study to measure positive and negative predictive values of this assay as an indicator of the presence of a tumor in normal subjects

- Genetic: Circulating tumor DNA assay
- type
- EXPERIMENTAL
- label
- Circulating tumor DNA assay - Second test- Negative result
- description
- Participants whose sample provided a positive result after first test, will be contacted immediately by telephone by an oncologist co-investigator and concurrently sent a letter by mail informing them of the result and asking them to return for a second blood draw. We expect that this communication will happen with about a month of the original blood draw. The letter will include contact information for the study team and the oncologist co-investigators, in case the participant has any questions or concerns at this stage. A requisition form will be sent with the letter. Two 10mL tubes of blood will be drawn at the blood collection visit, to allow repeat testing and confirmation that the mutation is present consistently. Once the data is analyzed, participants with a negative result will be sent an email thanking them for their participation and informing them of the negative result.
