What if Eosinophils Results Are High?
Elevated white blood cell levels in the blood can be an indicator of illness or infection. They are particularly useful in inflammatory allergic conditions such as asthma; a high eosinophil count alongside wheezing is associated with an asthma flare.
An elevated count can sometimes be transient, including when a person otherwise feels well. When levels remain elevated over time, this finding is often reviewed further to clarify the cause.
Higher counts can also occur in conditions such as asthma or vasculitis, and may be associated with feeling unwell.
What if Eosinophils Results Are Low?
An abnormally low eosinophil count can be linked to alcohol intoxication or to excessive cortisol production, such as in Cushing's disease.
Low eosinophil counts can also reflect time of day. Under normal conditions, eosinophil counts are typically lowest in the morning and highest in the evening.
This finding is often not considered clinically significant on its own.

What should I do If my Eosinophils test results are positive?
If your Eosinophils test results are positive, it means your eosinophils levels are elevated. This can be due to many health conditions, like an allergic reaction or infection. It's necessary to consult your healthcare provider who can interpret the results in the context of your symptoms and medical history.
How to interpret the Eosinophils test results?
Your test results will show the level of Eosinophils in your bloodstream. Elevated levels may indicate the presence of various conditions such as allergies, parasitic infection or autoimmune diseases. However, interpreting these results can sometimes be complex, and it is recommended to discuss the results with a healthcare provider.

Why would I need an Eosinophils test?
The Eosinophils test is helpful when investigating a range of health disorders. High levels of eosinophils can indicate allergic conditions, skin disorders, parasitic infestation or certain autoimmune diseases. Additionally, Eosinophils test might be beneficial for people experiencing symptoms such as unexplained fatigue, unexplained weight loss, rashes, or breathing difficulties.
What is the Eosinophils test kit?
The Eosinophils test kit is a medical diagnostic tool used to measure the level of Eosinophils - a type of white blood cell - in your bloodstream. It's a simple, at-home test that involves a small finger-prick to collect a blood sample. The kit is then returned to a UKAS accredited lab for analysis by medical professionals.
