One of my clients undertake Lead welding as one of their work activities. I have tried to arrange for the guys involved to get blood tests but have struggled locally and the Internet is not proving useful.
I was hoping someone might be able to recommend a company that will visit the workplace and take a blood test.
Thanks in advance

Try the RPS Group.

I have not used them myself for this, as we have an established supplier but I use them for other testing and they have quoted me for Lead testing.

Though not a direct response to this topic, it seems appropriate to mention that if high blood lead levels are found, they might not necessarily reflect inadequate controls at the affected person/s' known workplace.

In the late 1970s while with HSE an employment medical adviser (EMA) and I investigated a notification of an unusually high blood lead level or lead poisoning in a young man who worked in a vehicle radiator repair premises. We and also the employer were puzzled because the conditions at the premises were well controlled. However, we subsequently found that the man worked evenings and weekends at a scrap yard breaking up vehicle batteries to recover the lead plates from them. The lack of basic precautions for this work was compounded by the fact that he smoked and had little regard for personal hygiene. Thus, when smoking or eating fish & chips by hand, he was liable and over a relatively short time to ingest a significant amount of lead (lead compound). Also changing his clothes was apperently a rare event, with laundering being even rarer, so he was likely to have lead on his clothing from where it would transfer to his hands and ultimately his mouth.

I don't know/recall the outcome of the case, partly because of a transfer within HSE. The young man may well have been in hospital for a while, during which his exposure to lead would be curtailed and would have led to a reduction of his blood lead level.
