My cousin recently had a CBC blood test, and the report shows Normocytic Normochromic RBC with mild erythrocytosis. Should this be a cause for concern? What can be done to manage or treat this condition? He has experienced some weight loss. He previously underwent surgery for thyroid cancer, and his latest scan is clear. He also received RAI therapy with a 100 mCi dose, and he has been doing fine since then. Is this blood report something to worry about?

Normocytic normochromic RBCs are generally normal. Mild erythrocytosis could result from smoking, dehydration, or hypoxia. Since your cousin had thyroid cancer, regular monitoring is advised. Consult your doctor for tailored evaluation.

Hi madam, my son Virat regularly has cold and other related problems like itchy nose, rubbing eyes, and itching in fold areas such as under the neck, under the penis, behind the knees, and itchy scalp, especially when oil is applied. I have been using homeopathy medicines from Homeo Mall near my home, but there is no result. Recently, I visited Rainbow Hospital and they have given a few medications. If I do not give them even for one day, the itching increases. I have consulted many allopathic doctors, but there is no result. I have his blood test report from 9 months back, which shows eosinophils count is high.

Dear Sir or Mam, seven months ago I started having tightening and pain on the left side of my body, including my chest. I have taken a PFT, and my report shows early small airway obstruction. I have visited many doctors, but they have neglected it. I am still suffering from this.
