Blood Specimen Collection For Laboratory Assay Research

This observational study aims to understand how well blood samples collected from a fingerstick (capillary samples) compare to traditional blood draws from a vein (venous samples). Researchers will also look at how stable these fingerstick samples are over time when stored. This information is important because fingerstick blood collection is easier for patients and could make it simpler to get lab tests done. You can join if you are 18 or older, in good general health, and willing to provide both fingerstick and venous blood samples. The study is looking for 10,000 participants, but its current recruitment status is unclear.

Study design
This is an observational study planning to enroll 10,000 participants. It will compare capillary and venous blood samples.
What's involved
You will need to provide capillary blood samples via a fingerstick and venous blood samples. This includes both self-collection and collection by a healthcare professional.
Compensation
Not stated in the trial record.
Follow-up
The study will track the correlation between samples and sample stability for 10 years.

Eligibility criteria

Inclusion

Any gender, in good general health
Must be 18 years old or older, inclusive at enrollment
Must be willing to provide capillary blood samples via a fingerstick and venous blood samples, including self-collection and collection by a licensed healthcare professional
Must be able to read, understand, and willingly sign an Informed Consent Form (ICF) and complete a brief health questionnaire
Must be able to read, speak and understand English
Must be available to attend one study visit at Investigator's laboratory or a third-party laboratory designated by the Investigator or collect samples at home, at the discretion of the Investigator.

Exclusion

Individuals who are unable to provide a blood sample due to any illness
Individuals participating in another research study, that the Investigator feels may compromise study outcomes
Individuals having an acute or chronic disease or medical condition, including pregnancy, which could excessively increase study risk in the opinion of the Investigator or compromise study outcomes
Individuals who are unlikely to be available for the duration of the study

What this trial measures

  • Correlation between capillary and venous samples upon collection10 years

    R-value comparing the lab readings generated by venous and capillary samples for a specific blood analyte immediately upon collection

  • Stability of the capillary blood sample after storage on Days 1, 2, and 310 years

    Median error % to compare the difference in values of each capillary sample after storage for a certain period of time (e.g., Days 1, 2, and 3) for a specific analyte when compared to the lab reading generated by the venous sample immediately upon collection
