Which tube is associated with lead testing?

Explanation:
Lead testing requires tubes that won’t contaminate the sample with lead. Because lead is a trace element, even tiny amounts from the collection tube can skew results. Using tubes that are certified as lead-free eliminates this risk, so the measured lead reflects the patient’s level—not the container. The emphasis here is on the tube’s lack of lead, which is why lead-free tubes are the correct choice. (Other tube types may have additives or use cases that don’t guarantee absence of lead.)
