Danny Nelstadt

Danny Nelstadt is the husband of Frank Nelstadt.

History
Danny's husband, Frank, came into the ER with their daughter, Ella, when he had a very severe cough and sore throat. He'd had the cough for a few days and wasn't concerned, but Ella was worried and made him go to the hospital. While he was being examined, he had trouble breathing, which was resolved when he coughed up a blood clot which was shaped like a bronchial tree. When he started to struggle to breathe again, he was taken to have TPA injected to break up the clot. He was then diagnosed with Factor V leiden. As the condition is genetic, Danny immediately said Ella needed to be tested. They never wanted to know which of them was her biological father, but knew they needed to know if she had the same kind of condition, so she could properly maintain her health. The test came back positive, though Ella said it didn't matter because they're both her dads.
