Low protein levels shown in blood tests

Faye
Hi,
I am currently on holiday and my parents have just opened my 12 week screening results and sent me through a screenshot of the letter. It does say that all the tests have shown up negative. However I have lower than average protein levels and that I need to go for another appointment for possible aspirin treatment and addition monitoring scans.
Before I spend the rest of my holiday worrying about this, is it serious? What could the implications be? Has anyone had experience of this? A quick check on Google has scared me!
Thanks in advance
