Decision made = Medical Request or Rejection
No dear, Decission made is not Medical Request.
If you get the Decission Made, after the VO receives your Medicals, then it means they are issuing your visa...Mostly happens after you send you passport to VO (Having received Passport Request).
Decission made, Prior to Medicals or without any other communication from VO mean, Rejection.
Anyways, like some are posting that it might be an error on eCAS, so just wait if they VO Replies. IF (hopefully not) its a rejection, a letter is also received by the applicant in few weeks.
