What does a low count of basophils in the blood mean?

A low basophil count is not very common because basophils are the least common type of WBC (White Blood Cell) and they are not usually detected by electronic counters.

A low basophil count is called basopenia and if it is seen in successive test, it may suggest:

  • Stress reactions.
  • Pregnancy and ovulation.
  • Hyperthyroidism.
  • Severe allergies or infections.

Basopenia is very difficult to study because some electronic counters may not detect basophils in a blood sample so in many labs values of zero or very close to zero are considered in the normal range.

Basopenia or a low basophil count in the blood means:

  • Mild basopenia (0 - 20 /µl in adults):

    A mild basopenia is not a matter for concern unless it is seen in successive blood tests.

    In that case, it is important to notice if basopenia is followed by eosinopenia that may suggest acute infection or use of corticosteroids.

    It can also happen in case of hyperthyroidism after treatment with thyroid hormones.

Which factors can decrease the basophil count in the blood?

Some particular health situation and drugs may reduce your basophil count in the blood:

  • Pregnancy
  • Stress
  • Ovulation
  • Chemotherapy
  • Radiation therapy
  • Drugs
    • Antiarrhythmic agents
      • Procainamide
    • Anticoagulants
      • Heparin
    • Barbiturate
      • Thiopental
    • Corticosteroids
      • Cortisone
      • Hydrocortisone
      • Prednisone

Which diseases can decrease your basophil count in the blood?

The following diseases can explain a basophil count in the blood lower than normal:

  • Hyperthyroidism
  • Cushing's syndrome
  • Brucellosis
  • Acute urticaria
  • Thyrotoxicosis

What can I do to increase the basophil count in the blood?

A low basophil count in the blood is very rare and it sometimes may be due to the inability of electronic counter to discern a small amount of basophils in the blood sample.

For that reason, basopenia is not a matter of concern about and it is not necessary to take any measure.

Which values are considered a low basophil count in the blood?

The following values are considered to be above the normal range:

IMPORTANT: These levels are expressed in number /µl (microliter). They are an example of a healthy white man/woman of about 45 years old with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
