So, your doctor never explained: CBC edition.

Great video!! I have been trying to find a video that broke down what exactly they are looking at.Seems like it is hard to find resources to help people become their best health advocate

[@drmarkheisig]

I'm glad this video was helpful!🙏🤙 Was there anything missing that you'd like to see in future videos? (*without giving overt medical advice)

[@TeamHoneyBadger1pt0]

Wow great video! I just got a blood test done last week, coincidentally. Gonna have to look into my RDW which is also low normal. Doctor didn’t even mention it

[@drmarkheisig]

Thank you for the kind words. And, be sure to ask your provider for an explanation. I'm sure they can tell you why they were not concerned with telling you. (Remember, each of these metrics is looked at in the context of the other CBC metrics (and even other "non-CBC" tests' e.g., Ferritin).) Thanks for watching!

Please explain her eosinophils reference range and reference range number, please.

[@drmarkheisig]

As mentioned in the video, eosinophils are associated with allergies (and/or "mast cell things") and parasites. The relative % is not established but shows trends relative to other WBCs (e.g., neutrophils and basophils). The absolute for this person was 0.4x10^3 cells per microliter (uL). That's upper limit of normal, and... totally normal.
