  The DROP-AD project involved 337 participants and demonstrated strong correlations between dried blood spot samples and standard venous blood draws.

• 3

  Dried blood spots can be collected at home, stored at room temperature, and shipped without refrigeration, addressing logistical barriers.

• 4

  Preliminary data showed high concordance between self-collected samples and professionally collected specimens, despite some collection failures.

• 5

  The method requires further refinement for clinical use but shows promise for research, population screening, and therapeutic trials.
