@angelsue My kiddo tested just below the limit for emergency medical intervention (39 and immediate chelation therapy is recommended at 45). We live in a home that was built in ~1865 in New England, where lead paint is a widespread problem and testing is automatically done at 1 and 2 years. It's not at all uncommon to have elevated lead levels, it's the most common serious health problem for kids in this age range here. Despite that, I didn't know it was such a huge problem or that we were at serious risk of lead poisoning, it was devastating to get those results. We've spent months mitigating the risks on our own and are participating in a state program to have our entire house (interior and exterior) remediated for lead. It's going to cost $70k. My kid is still testing higher ( ~10) after a year but is so far ahead of his age group developmentally, and we're hoping the number continues to go down. I learned a lot from the numerous inspections and interventions we've had with the state health department, and bottom line is lead is everywhere. Even modern paint isn't lead free, it's just a lower amount, and exterior paint still has higher amounts than you think. The main risk factor isn't actual lead paint chips either, it's lead paint DUST which is dispersed from any rub point that has lead paint in it, so doors and windows opening and closing are the usual culprits. Dirt outside, dust in your house, and even dust from roads are high in lead if you live in an area where old houses are common. Washing hands, toys, not touching windows, not eating dirt (you know, accidentally) or gardening in untested dirt, and always using lead safe practices when doing any kind of renovation or house project are absolutely necessary to protect kids from lead poisoning. It's been a horrible experience and I had no idea we were at such risk, luckily my kiddo is okay but we have had over a year of trying to solve this problem and we're still not done.
