Basophils are rare white blood cells that help your body respond to allergies and inflammation.
Basophils are the rarest white blood cells. They release histamine and other substances during allergic and inflammatory reactions, helping shape the body's response to allergens.
This test reports the absolute basophil count, the actual number in a set volume of blood, from the differential part of a complete blood count.
Basophil counts are usually very low. A raised count can appear in allergic and inflammatory conditions and, less often, in certain blood disorders. Because the numbers are so small, this marker is most useful read together with the rest of the white cell differential.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
Typical adult range, automated count:
| Measure | Typical range |
|---|---|
| Basophils, absolute | 0.01 to 0.1 x10^9/L |
Ranges are guidance only and vary by laboratory and analyser. Read against your lab's own reference range, aligned to German practice (DGKL).
Your result shows whether your basophils are in the usual low range or raised. Alongside the rest of your blood count it helps flag an allergic or inflammatory process worth a closer look.
Because counts are so low, small changes can look large in percentage terms. Allergic reactions and some inflammatory conditions raise them. Delays before analysis can affect the result.
Best read with the rest of the white cell differential, especially eosinophils, and with the clinical picture.
What does a high or low basophil result mean? High may relate to allergies, inflammation, or certain marrow changes. Low often reflects stress, illness, pregnancy, or steroid use.
Do I need to fast for this test? No. Fasting is not required for basophils or the CBC differential.
Which medicines or habits can affect results? Steroids can lower basophils. Recent infections, intense exercise, smoking, and dehydration can also shift white cell counts.
How often should I test basophils? Usually when a clinician orders a CBC for symptoms or routine care. Abnormal results are often rechecked to confirm trends.
How long do results take? Results are usually ready in about 7 days.
What should I discuss with my clinician? Share symptoms, allergies, recent illnesses, and all medicines. Ask whether to repeat testing and review other white cell types for context.
