Bought a 1920s home with lead a paint, had it professionally tested. Some rooms have high exposure 11-12 with XRF (obviously dangerous) while some areas have 0.2-0.5 positive levels but they say are safe even areas marked 0.9 +- 0.2. My wife thinks lead in the paint is still lead in the house and wants it all removed. Idk how to explain why the lower levels shouldn’t matter vs when the higher level are so toxic. While we don’t have kids now, she wants to get pregnant in about 6 months, so the lead exposure is weighing heavily on her thoughts and concerns right now.

Lead is lead!!! Your wife is right, some.
The reason we set lead levels somewhere and call it safe is because you have to work thru government and lobbies to set a standard. While there is some science behind those levels, usually there is more political lobbing and compromise.
Ideally 0 is best, however, very hard to reasonably achieve without a lot of work and money. So they set a level which is achievable , that an average person body can process, without much long term effects. This is generally based on an adult male in good health. Women, children, pregnant women, immune compromised, all require different levels since their body is different.
