Brief Answer:
viral infection can cause a low white cell count temporarily

Detailed Answer:

Hi,

Viral infections can sometimes cause a low white cell count. With infections, a high white cell count is normally expected but the opposite can occur in some viral infections. Since viral infections are the most common infections in childhood, it is possible that this may be the cause for him. It would normally improve on its own if this is the case.

Infection is the most common reason. Other causes include side effect of medication or an abnormality of the bone marrow.
However, these are not as likely. If a viral infection is the cause, he should be fine.

I hope this helps, feel free to ask any other questions.

Brief Answer:
Not likely; they normally have an initial very high white cell count.

Detailed Answer:

Hi,

Though leukemia can cause a low white cell count, usually, at the time it is diagnosed, the white cell count is very very high.

Leukemia is an over production of white cells. Eventually the bone marrow maybe overwhelmed and the values may go down but normally, initially the WBC is very high.

Hope I have answered your query. Let me know if I can assist you further.

Thank you.

Brief Answer:
It will improve on its own and will not cause him any symptoms.

Detailed Answer:

Hi,

As mentioned above, it can also occur as a result of some medications and if the bone marrow is not working well. The bone marrow is responsible for production of the blood cells.

There is nothing that you can personally do to help raise his white cell count and the low count itself is not going to cause him any symptoms. As he continues to get over whatever infection or illness he had, his body will improve on its own.

It will take a few weeks, this is why the doctor will wait a little while before repeating it.

Hope I have answered your query. Let me know if I can assist you further.

Thank you.

Have a question im 42 year old female I have blood in urine it’s 11/30 is that abnormal and what can be thecause
doctor
Answered by Dr. Michelle Gibson James (4 hours later)
Brief Answer:
A urine analysis may be needed and imaging.

Detailed Answer:

Hi,

It is a small amount of blood but blood is not typically supposed to be present in the urine so even a small amount is considered a little abnormal.

In many cases, however, it is not related to a serious medical condition. Blood in the urine is called hematuria.

Some of the more common causes are:

(1) Infection of some aspect of the urinary tract or a genital infection Eg: even a vaginal yeast infection

(2) Trauma

(3) Side effect of medication Eg: Aspirin or other meds to decrease clotting

(4) Stones in the kidney, bladder or other aspect of the urinary tract

(5) Due to period

(6) A mass

(7) Cysts in the kidneys

(8) Blood disorder

(9) Kidney disease

If the bleeding continues, then your doctor may sens urine to the lab for analysis and may suggest an ultrasound to take a look.

It is not serious for most persons and a cause is not found in some persons.

Hope I have answered your query.

Thank you.
