Is there any consequences for not doing a court order hair follicle test done within the time period given?

My husband and his ex are going to court for child custody. His lawyer submitted evidence of his ex wth a weed pipe while she had their children in her care. The judge court ordered the both of them to do a hair follicle test within 72 hours of the court order. My husband did his, and it came back negative. His ex got hers done a week and a half after the time frame given, but her came back negative as well. Is there any sort of consequences for her not doing the hair follicle done within the 72 hours?
