Read first · FDA's statement on these data

Adverse event reports submitted to FDA do not undergo extensive validation or verification. Therefore, a causal relationship cannot be established between product and reactions listed in a report. While a suspected relationship may exist, it is not medically validated and should not be the sole source of information for clinical decision making or other assumptions about the safety or efficacy of a product. Additionally, it is important to remember that adverse event reports represent a small percentage of total usage numbers of a product. Common products may have a higher number of adverse events due to the higher total number of people using the product. openFDA, FDA

FDA adds: "Although MDRs are a valuable source of information, this passive surveillance system has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data. In addition, the incidence or prevalence of an event cannot be determined from this reporting system alone due to potential under-reporting of events and lack of information about frequency of device use." And: "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices."

Do not rely on openFDA to make decisions regarding medical care. While we make every effort to ensure that data is accurate, you should assume all results are unvalidated.

FDA's MAUDE database holds 188 reports that name the brand "Cell-Dyn 3700 Sl Analyzer" (automated hematology analyzer), received between March 2008 and August 2018; the manufacturer given most often on reports is Abbott Diagnostics Division. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, and none in the 12 months before.

The event types recorded are malfunction (96.3%), injury (3.2%) and death (0.5%); across all counter, differential cell reports (product code GKZ) death is recorded in 0.1% and malfunction in 95.7%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device misassembled during manufacturing /shipping (28.2%), other (for use when an appropriate device code cannot be identified) (9%) and break (6.9%). The patient problems coded most often are no patient involvement, eye injury and caustic/chemical burns. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
