With a strong family history of lupus, and some symptoms arising would it be wise to be tested for it at the age of 27?
Yes it is wise to... Lupus is so called the master of disguise. It can mimic so many different diseases and can cause quite a bit of disability if left untreated. It is not curable but treatable. Testing is simple and so it is wise to do so since you are reporting to have some symptoms already. It can have a negative impact on pregnancy as well. So, consult your doc. Good luck.
Yes. The usual tests are blood work. Very easy to do. This would not be a hard test so get it done.
