From Peoria, Arizona, USA:

Our eight-year-old daughter was diagnosed with type 1 last June. We recently had our other child tested to see if he had any of the antibodies that can lead to type 1. His test has come back positive for one of four antibodies. Can you tell me a percentage of how this increases his risk of getting type 1? Of children that have tested positive for an antibody, what percent develop type 1? Also, how can you have the antibody one year and the next it can disappear?


The antibody tests are not perfect and you are correct that sometimes it can vary and be positive, negative etc. The more positive the results, the higher the risk. The more antibody tests that are positive, i.e., different antibodies, also the more risk. You would have to discuss the specific details with your pediatric diabetes team since they would have the actual values and be able to give you some risk analysis.
