It sounds like you have some valid concerns and questions regarding your blood type history. To clarify, your blood type typically does not change throughout your life under normal circumstances. The most likely explanations for the discrepancy between your childhood records showing "O+" and your recent test that indicated "A+" could be related to either an error in blood typing or an incorrect record in the past.

Explanation:

1. Blood Type Consistency: Blood type is determined by genetics and remains constant. It is unlikely to change unless there's a specific medical intervention such as a bone marrow transplant, which doesn't seem to apply in your case.

2. Testing Errors: The testing methods used decades ago, especially in neonatal care, might not have been as precise as they are today. Human errors in documenting or testing can also happen, leading to discrepancies.

3. Documentation Issues: It's possible that incorrect information was recorded at birth. Mistakes in labeling blood type on hospital documents, especially in the NICU with high-stress conditions, can occur.

Next Steps:

1. Confirm Your Blood Type: If you want clarity, consider getting another blood test done at a reputable laboratory. Ensure that the laboratory follows standard blood typing protocols to minimize the risk of errors.

2. Look Over Old Records: If possible, check for any previous medical records or documents that may provide additional information or confirm your current blood type.

3. Consult with a Healthcare Professional: If you have further concerns about this discrepancy or if you have other health questions related to blood type, discussing your concerns with a healthcare provider can help provide tailored guidance.
