** 1. Neutropenia is a condition in which the neutrophils in the bloodstream is decreased affecting the body s ability to fight off infections, while neutropenia itself doesn t produce symptoms but infections [bacterial] can occur as a complication of neutropenia and since it is mild i.e. ANC [absolute neutrophil count is ranging from 1000-1500/microL PS: common causes of neutropenia are typhoid/paratyphoid fever, viral infection, bone marrow depression. 2. The presence of TPO [thyroid peroxidase antibodies] in your blood suggests that you are suffering from some thyroid disease and the cause is an autoimmune disorder, such as Hashimoto s disease or Graves disease. [ since you have normal TFT with TPO antibodies, your doctor may recommend periodic checkups to watch for future thyroid problems.] and for that thyroglobulin test is considered PS: i. AntiTPO measurement may be appropriate for patients with high-normal TSH to help distinguish those at risk of developing true hypothyroidism. [One or more thyroid antibody tests may also be ordered if a person with a known non-thyroid-related autoimmune condition, such as systemic lupus erythematosus, rheumatoid arthritis, or pernicious anemia,develops symptoms that suggest thyroid involvement.] ii. Carbimazole used in the treatment of overactive thyroid causes neutropenia and agranulocytosis, [keep in mind, if prescribed] iii. These tests are used to help the doctor determine whether the baby may be at risk of thyroid dysfunction since thyroid antibodies can cross the placenta and cause hypothyroidism or hyperthyroidism in the developing baby or newborn. [since losing significant weight, probably hyperthyroidism is possibility] 3. since which type [whether conjugated or un conjugated or total] bilirubin is raised is not mentioned thus cannot say for sure that whether cause is pre hepatic or intra/post hepatic.
