What a report is

A report is not proof that the device was the cause of the event.

FDA says:

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.

FDA also says:

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.

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.

Reports on file

Product code GKP is the FDA classification for Instrument, coagulation, automated. The panel is Hematology. The device class is 2.

From December 1994 to June 2026, FDA received 661 medical device reports that have this product code.

FDA received 1 report in the 12 months to September 2026 and 4 in the 12 months before. FDA releases MAUDE data every month. Reports can arrive months after an event, so the newest months grow in later releases.

The number of people who use the product is not in the data. A count is not a rate.

Product code

FDA gives each type of device a product code of three letters. A report has the code of its device, so a code has the reports of each brand of one device type.

Device class

Class I, II or III is the regulatory class of FDA for the device type. It is not a rating of a product.
