  Hi da celeb,
  
  I don’t understand your question but I can try answering you.
  
  Genetic tests can be used to confirm the presence of an Alzheimer’s gene in a patient who already has symptoms ( also called diagnostic DNA testing). Testing can also predict who will develop the disease in the future e.g. someone with a family history of the disease (also called predictive testing.)
