The truth is that you are legally entitled to know your results. There ARE rare circumstances in which they may withhold them but it’s unlikely to apply to you.
Look up the hospital on the internet where you gave your blood test and search for ‘Subject Access Request’ and it will tell you how to apply. It’s a simple free letter you send and the hospital is legally obliged to provide the information requested.
It’s something I have done many times. I was MGUS for over 10 years and, to be fair, most times I was told the results. I kept a spreadsheet and it was reassuring. Very recently I noticed something the hospital hadn’t picked up and I’m now deluged with hospital appointments. Almost inevitably it’s amyloidosis.
Do it once or twice and they’ll realise it’s easier to give you the results in the first instance.
