st: Hausman test

I have a data set consisting of various laboratory measurements, characteristics (sex, age) and dietary data on related individuals from several families. 
I am interested in modeling cholesterol and because of the correlation within families I used -xtreg, re- (GLS) regression. However when use a Hausman test to compare the fitted model with a -xtreg, fe - model, I get p=0.00024. 

My understanding is that I should not use the random effects model, but should be using the fixed effect. What is the implication if I ignore the Hausman test and report results from the random efects model?

Thank you,
