Leukocytosis

Hello Doctor, my girlfriend recently went to the hospital for a blood test and found that her white blood cell count is elevated.
Is there anything I should be aware of? Her father passed away from blood cancer and bone cancer, which was attributed to an overdose of contrast agent given by the physician, and her mother also passed away from breast cancer, so I am a bit worried.
I would appreciate any guidance you can provide.
Thank you.

You, 10~19 year old female. Ask Date: 2018/01/24

Dear Mr.
You:
Certain types of breast cancer, blood cancer, and bone cancer may be related to genetics or family history; however, the evidence is not always definitive.
Nonetheless, physicians will still take this into consideration during medical history inquiries.
Many cases of leukemia (blood cancer) present with elevated white blood cell counts, particularly abnormal white blood cells, which can often be observed in peripheral blood smears, bone marrow smears, or bone marrow pathology slides for diagnostic purposes.
Generally, elevated white blood cell counts are primarily due to infections or inflammatory responses; if blood cancer is suspected, the aforementioned tests must be conducted.
Therefore, it is recommended that your girlfriend visit a hematology department at a hospital for further evaluation to clarify the issue.
As for whether you could be infected, there are currently no relevant records or literature in the medical field regarding this.
The likelihood of experiencing a reaction, including shock, from the injection of contrast agents is low; however, such incidents have occurred in many hospitals or medical centers.
Common risk factors include renal insufficiency, certain medications, and allergic predispositions, among others.
In the past, ionic contrast agents were more commonly associated with such reactions, while non-ionic contrast agents have been used less frequently in recent years, though reactions can still occur.
This remains an area that the medical community must continue to address collaboratively.

Elevated white blood cell (WBC) counts can be a source of concern, especially in the context of a family history of hematologic malignancies, such as leukemia and lymphoma. Understanding the implications of elevated WBC counts requires a comprehensive approach that considers various factors, including the specific WBC count, the differential count (which breaks down the types of white blood cells), clinical symptoms, and the patient's medical history.

Firstly, it's important to note that a normal WBC count typically ranges from about 4,000 to 11,000 cells per microliter of blood. An elevated WBC count, known as leukocytosis, can occur for various reasons, including infections, inflammation, stress, allergic reactions, and more serious conditions like leukemia. In your girlfriend's case, the context of her family history adds an additional layer of concern, but it does not automatically indicate that she has a serious condition.

When interpreting elevated WBC counts, the differential count is crucial. This breakdown includes neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each type of white blood cell plays a different role in the immune response. For instance, neutrophils are typically elevated in bacterial infections, while lymphocytes may increase in viral infections or certain types of leukemia. If the report shows a predominance of immature cells (blasts), this could indicate a more serious condition, such as acute leukemia.

In addition to the WBC count and differential, it is essential to consider any accompanying symptoms. Common symptoms associated with elevated WBC counts can include fever, fatigue, unexplained weight loss, night sweats, or persistent infections. If your girlfriend is experiencing any of these symptoms, it would warrant further investigation.

Given the family history of blood cancers, it is advisable for your girlfriend to consult a hematologist or an oncologist. These specialists can provide a more detailed evaluation, which may include additional blood tests, bone marrow biopsies, or imaging studies to rule out malignancies. They can also assess if the elevated WBC count is a transient response to an infection or inflammation, or if it requires more serious consideration.

Moreover, lifestyle factors should not be overlooked. Stress, diet, and overall health can impact blood counts. Encouraging your girlfriend to maintain a healthy lifestyle, manage stress, and follow up with her healthcare provider for regular check-ups can be beneficial.

In summary, while an elevated WBC count can be concerning, it is essential to interpret this finding in the context of the complete blood count, differential, clinical symptoms, and family history. Prompt consultation with a healthcare professional specializing in hematology will provide clarity and guide any necessary further investigations or interventions. It is understandable to feel anxious given the family history, but many cases of elevated WBC counts are benign and can be managed effectively with appropriate medical guidance.
