Increased eosinophils? Leukemia?


Hello Doctor: At the end of 2012, I had a health check at Taichung City Hospital, and the results that were flagged were: Eosinophil percentage 4.0% (reference range 0.2–1.4%) and Eosinophil count 0.3 (reference range 0.0–0.2 x 10^3/uL).
All other values were normal.
Later, at the beginning of this year, I had another blood test at a general laboratory, and the Eosinophil percentage was 1% (reference range 0-1), so this item was no longer flagged.
However, another test showed a red flag: Mean Corpuscular Hemoglobin 31.37% (reference range 32-38).
I am a bit worried because my cousin passed away from leukemia; should I undergo more detailed examinations? Additionally, today I have been sneezing a lot and later noticed that I had a nosebleed on the left side.
After a while, the nosebleed stopped, but I felt something in my throat that I thought was phlegm, and when I expelled it, it turned out to be a blood clot about 1 cm in diameter (not coughed up).
This happened once a few months ago as well, so I quickly went to an ENT specialist.
The doctor noted a slight fever, sore throat, and some swelling in the throat and nose, and prescribed medication for three days before a follow-up.
Furthermore, in the past month, I have experienced bloating and stomach pain four times after eating; should I undergo more detailed blood tests? Is there a possibility of leukemia? (I have gallstones, but a doctor at Changhua Hospital believes the pain is not from gallstones based on my description.) Thank you, Doctor.

Dear Betty: If you are concerned about leukemia, please go to the hematology department to schedule a blood test.
We cannot make a diagnosis without proper examination.
For the nosebleeds, please see an otolaryngologist to determine whether it is a nasal mucosa issue or a potential nasopharyngeal cancer.
As for your stomach pain, you should visit a gastroenterologist.
Thank you!

Elevated basophils in your blood test results can understandably raise concerns, especially given your family history of leukemia. However, it's essential to interpret these findings in context and understand what they might mean for your health.

Basophils are a type of white blood cell that plays a role in your immune response, particularly in allergic reactions and inflammation. A normal range for basophils is typically between 0.2% and 1.4% of your total white blood cell count. Your initial result of 4.0% is indeed elevated, which can be concerning, but it's crucial to note that basophilia (elevated basophils) can occur for various reasons, not just leukemia. Common causes include allergic reactions, chronic inflammation, infections, and certain hematological disorders.

In your follow-up test, the basophil percentage dropped to 1%, which is within the normal range. This fluctuation suggests that the initial elevation may have been temporary or related to a specific condition at that time. It’s also worth noting that basophils are typically the least common type of white blood cell, and their levels can vary based on numerous factors, including stress, infections, and allergic reactions.

Regarding your concerns about leukemia, it’s essential to understand that leukemia is characterized by a significant increase in abnormal white blood cells, which often leads to symptoms such as fatigue, frequent infections, easy bruising or bleeding, and unexplained weight loss. While elevated basophils can be associated with certain types of leukemia, they are not a definitive indicator of the disease. A comprehensive evaluation, including a complete blood count (CBC) and possibly a bone marrow biopsy, would be necessary to diagnose leukemia accurately.

Your recent symptoms, including nosebleeds, throat discomfort, and gastrointestinal issues, warrant further investigation. The presence of blood clots from your throat and recurrent nosebleeds could indicate an underlying issue that needs to be addressed. It’s good that you’ve consulted an ENT specialist, as they can provide insights into whether these symptoms are related to allergies, infections, or other conditions.

As for your gastrointestinal symptoms, such as bloating and pain after meals, these could be related to various factors, including dietary choices, stress, or even gallbladder issues, especially given your history of gallstones. It would be prudent to discuss these symptoms with your healthcare provider, who may recommend further tests, such as an abdominal ultrasound or additional blood work, to rule out any significant issues.

In summary, while elevated basophils can be concerning, they are not a definitive sign of leukemia, especially given your recent normal results. Your symptoms should be evaluated in conjunction with your overall health and medical history. It’s advisable to continue working closely with your healthcare providers, who can guide you through the necessary tests and evaluations to ensure your health concerns are addressed appropriately. Regular monitoring and open communication with your doctors will help alleviate your worries and provide clarity regarding your health status.
