    • Ongoing Z-0162-2027 FDA Not yet classified initiated 4 Sep 2026

    In kit sub-lot 2530M-01 the date of expiration printed on the outer labeling may indicate the wrong expiration date of July 22, 2026 while the correct expiration date is July 13, 2026. If used the system will display an error message and prevent the operator from running the test. Resulting in delayed results.

    • Ongoing Z-1895-2026 FDA Class II initiated 13 Mar 2026
    • Ongoing Z-1893-2026 FDA Class II initiated 13 Mar 2026

    Customers reported observing unexpectedly elevated results when using certain third-party micro-collection devices to collect capillary samples for testing with the LeadCare Test Systems. False positive lead results may cause delayed results and additional unnecessary testing.

    • Ongoing Z-0584-2026 FDA Class II initiated 23 Feb 2024

    Calibration Buttons being used in the kitting process were incorrectly labeled as Lot 2323M for lot 2333M. The use of mislabeled calibration Button with Lot #2333 can lead to delayed or erroneous high or erroneous low results.

    • Ongoing Z-0219-2024 FDA Class II initiated 19 Sep 2023

    During an internal audit a small percentage (<10%) of plastic caps used to close the treatment reagent tubes were found to not meet the minimum dimensional lip requirement and may have inadequate cap-to-tube seals. Manufacturing with these caps may result in cap-to-tube seals that allow leaking of HCl or may result in cap-to-tube seals that allow evaporation of treatment reagent. The consequence of this would be a change in the volume of treatment reagent and a change in the ratios of either added patient sample or control material to treatment reagent. The result of this might be a falsely elevated result (e.g., a patient false positive [PATFP] result or a Controls Out of Range-High [COOR-Hi] result).

    • Ongoing Z-1597-2022 FDA Class II initiated 25 May 2022

    Facility Temperature excursions (from June 2021-August 2021) prior to delivery; exposure to higher temperatures may have impacted product effectiveness. All lots received between 06/01/21-9/30/21.

    • Terminated Z-1952-2021 FDA Class I initiated 7 May 2021

    Magellan has received reports that control tests of either the Low-Control and/or the High-Control generated a low result. The issue may cause the underestimation of blood lead levels in patient samples.

    • Terminated Z-0285-2019 FDA Class II initiated 8 Aug 2018

    Defect with the calibration button for lot 1808M. Level 1 and Level 2 Quality Control (QC) values will generate results of HIGH (>65 g/dL). Results for patient testing with this lot will be displayed as HIGH.

    • Terminated Z-1295-2018 FDA Class II initiated 9 Jan 2018

    The incorrect placement of AA batteries into certain LeadCare II Blood Lead Analyzer may cause the batteries to overheat, and the chance that a user could burn their fingers if the batteries are removed while hot.

Questions

AI-generated answers, 6 Oct 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

  • What is the Leadcare II Blood Lead Testing System used for?

    The Leadcare II Blood Lead Testing System is designed for the quantitative measurement of blood lead levels, providing results from capillary or venous blood samples to support clinical assessment of lead exposure in point-of-care settings such as laboratories and clinics.

  • How is the Leadcare II Blood Lead Testing System supplied and what sample type does it require?

    The system requires only two drops of blood, which can be either capillary or venous, and is intended for use as a point-of-care analyzer where minimal sample volume and rapid results are needed for blood lead testing.

  • Is the Leadcare II Blood Lead Testing System reusable or single-use, and how long does it take to produce a result?

    While the analyzer itself is reusable for multiple tests, each test requires a single-use cartridge, and the system delivers a quantitative blood lead result in approximately three minutes after sample application.
