Patient's Query

Hi doctor,

My report shows an infection, but I need to know which type of infection or which organ was infected? So, I can consult a doctor related to this department. I am taking medicine for this infection.

I appreciate any help you can provide.

Hi,

Welcome to icliniq.com.

The possible causes are bacterial, viral, and parasitic. In the new report (reports removed to protect the patient's identity), you have lymphocytosis, suggesting infection. You also have borderline eosinophils, which indicate a possible allergic cause. Platelets are low in both old and new reports.

MCH (mean corpuscular hemoglobin) and MCHC (mean cell hemoglobin concentration) are high, with the possibility of macrocytic anemia. Still, hemoglobin is normal and may likely be due to multiple causes, including folic acid and vitamin B12 deficiencies.

However, I suggest having additional tests,

1) Blood- Erythrocyte sedimentation rate, CRP (C-reactive protein), and vitamin B12.

2) Urine- culture, sensitivity, and routine.

3) X-ray chest- PA (posteroanterior) view.

Medications- You also have not mentioned what medications were taken, as you mentioned infection-related tablets.

Please revert with clinical details to discuss and decide on a course of action.

I hope this helps you.

Thank you.
