With the symptoms and family history, yes, I would have her tested.
However, testing is not as accurate in younger children. Even if the tests are negative, she could still have it.
The blood tests you want are the FULL Celiac panel. It involves five tests. Make sure that your dr orders them all.
Anti-gliadin antibodies (AGA) both IgA and IgG
Anti-endomysial antibodies (EMA) - IgA
Anti-tissue transglutaminase antibodies (tTG) - IgA
Total IgA level.

http://www.celiacdiseasecenter.columbia.ed...nts/A02-FAQ.htmQ: Why do my family members need to be screened for celiac disease?
When the diagnosis is established in one family member, their first- degree relatives (parents, siblings and children) should have blood tests for celiac disease. This is because at least 10% of family members will have the disease, even if they are asymptomatic. Screening is also recommended for second-degree relatives (grandparents, grandchildren, aunts, uncles and cousins) as they are also at an increased risk for celiac disease. Family members who already have an autoimmune disease are at a greatly increased risk to have celiac disease (25%).
The reasons to diagnose family members prior to the development of symptoms include the prevention autoimmune diseases and malignancy.
(Your husband should also be tested since his father has it).
The main thing to do is to keep her eating gluten. Don't take gluten out of her diet until AFTER all testing is complete. Testing requires gluten to be in the system.
Best of luck, and I hope you find answers regardless of what the issue is!
