Venous Blood Lead Test Not on the Level

Raise your hand if you’ve performed venous blood lead tests using Magellan Diagnostics’ LeadCare analyzer recently.

If your hand is up, it’s possible that those tests may have returned underestimated blood lead levels, according to a national health advisory the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) issued last month.

Now, most Texas physicians won’t have to worry about this. The Department of State Health Services (DSHS) manages the Texas Childhood Lead Poisoning Prevention Program (CLPPP) and doesn’t use the Magellan Diagnostics analyzer.

Furthermore, the advisory does not apply to capillary blood tests, which — as you know — are collected by finger stick or heel stick.

But if you are concerned that you might have administered an underestimated blood lead test, there are a couple of things to do, according to FDA, CDC, and DSHS:

First of all, stop using Magellan Diagnostics’ LeadCare analyzers for venous blood samples.

After that, retest the following patients whose initial venous blood tests — that’s venous, remember — were analyzed using Magellan Diagnostics’ LeadCare: 

  • Children younger than 6 years at the time of the alert, May 17, 2017, who had a lead test result of less than 10 micrograms per deciliter; and
  • Pregnant or lactating women.    

All other adults who are concerned should talk to you about whether to be retested. 

If you still have questions, contact CLPPP at (512) 776-7268.
