Hello from JustAnswer.
These are three different issues.
Thyroid peroxidase, or TPO, in an enzyme in the thyroid, and antibodies that develop to this enzyme occurs in certain autoimmune
conditions. A result of 177 is significantly elevated. If the thyroid function tests, such as TSH, T4, and T3, are abnormal, then an elevated TPO antibody level indicates that the reason for the abnormality is autoimmune inflammation of the thyroid. However, if the thyroid function tests are normal, it identifies a group of people at increased risk of developing dysfunction in the future. It does not require any current care, but it is a reason for routine ongoing monitoring of thyroid function.
An absolute eosinophil count of 512 is normal in may labs, but since you have included it, it apparently is considered abnormal in this lab. You do not say the normal range, but this is probably mildly elevated relative to the normal range, so is likely not an issue. About 5% of normal people will have a result that is only mildly abnormal, and this is not a concern. If the eosinophil count is significantly elevated, it is most often due to allergies, although there are certain infections that can also increase the eosinophil count.
A vitamin D level of 26 is not yet deficient, which would involve a level below 20. However, a level in the 20s is considered borderline low, or also called vitamin D insufficiency. The usual treatment is vitamin D replacement and monitoring to assure that the level corrects over time.
If I can provide any further information, please let me know.
