More than likely, yes.The most common reasons for a postponement are:Awaiting a regular smear after an abnormal smear or an LLETZ or colposcopyReferred for a heart check, e.g. cardiac MRI, ECG, or EKGBreast check screen/mammogramThe above is only a sample..If your medical report contains a referral for further investigation by a specialist, there will be an issue even if this referral is years old. Before you apply, you should check with your GP and if the referral is no longer required, make sure they note this on your medical report. Otherwise, the insurer will postpone until the appointment has taken place.
