Handheld XRF scanners can detect lead and other heavy metals. But they cost more than $10k. A lead remediation contractor probably will have one of these so they can tell what paint has lead in it, what needs to be removed. Also many government building inspectors will have these scanners.
There are lead test kits with a marker like swab. You can test painted surfaces, things like dust, it takes about a minute and turns red if there is lead. A 2 pack is $11 at the hardware store here in the US. There are also test kits you wipe for lead dust, or send paint fragments and send it off to be tested. In many areas these are free or subsidized by the local government. In the US a non subsidized test kit is around $5 to buy, and around $30 to send to a lab.
Also lead paint can be safely "encapsulated" and painted over in most cases. It is really only an issue for door frames or window frames where the paint can turn to dust, or where paint is peeling or chipping.
