The Complete Blood Count with Differential (CBC w/ Diff) is the most commonly ordered blood test. It counts your red blood cells, white blood cells, and platelets, and provides a detailed breakdown of the five types of white blood cells. This helps detect infections, anemia, clotting disorders, immune system conditions, and blood cancers.

15 biomarkers tested
Your CBC with Differential results will include values for each of the 15 biomarkers tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 1–3 business days.
