Complete Blood Count Test (CBC)

Clinical significance

Eosinophils are a kind of white blood cell that helps fight disease.

The count may range a bit between different laboratories, but a normal range is usually between 30 and 350 cells/µL or 0.02 - 0.35 10⁹/L. A count of more than 500 cells per microliter (cells/µL) of blood is considered eosinophilia.

Mild to moderate and marked or severe eosinophilia are defined as 5% to 15% (0.7 to 5 10⁹/L) and greater than 20% (5 x 10⁹ cells/L) of circulating granulocytes, respectively.

What causes eosinophilia?

  • Allergies and asthma.
  • Drug allergy.
  • Infections (mostly from parasites)
  • Blood disorders and cancers.
  • Autoimmune disease.
  • Endocrine disorders.
  • Diseases involving organs and systems, including the: Skin. Lungs. Gastrointestinal system. Neurological system. Joints, muscles and connective tissue. Heart.

My journey back to health with Healsens. Thank you!!

That's when I turned to a nutritionist and ordered a blood test through Healsens. … Four months later, I retested. My biological age dropped to 24—nearly a decade younger than my real age.

Useful app to track analytics and 2nd opinion

It helps me track main parameters, understanding what do they mean and correlations, and make critical analysis to make preventative changes. Hope too see new fichas soon!

Everything is great! Excellent app! It's very convenient for storing all your test results! The only thing I wish was that you could record blood pressure readings for both arms, as this is sometimes important for blood pressure monitoring.

A useful app. It motivates me to lead a healthy lifestyle and monitor my diet. After the test results, I decided to change my diet – I cut out flour and chocolate. I lost 2 kg in about a week. We'll see how the test results look over time.
