The device description and performance studies focus on a standard immunoassay for measuring a biomarker. There is no mention of AI or ML in the intended use, device description, or performance evaluation.
No.
The document states that the device is a Chemiluminescent Enzyme Immunoassay (CLEIA) for the quantitative measurement of CA 19-9, to be used as an aid in the management of patients diagnosed with cancer, not for direct treatment or therapy.
Yes
Explanation: The device is used for the quantitative measurement of CA 19-9 as an "aid in the management of patients diagnosed with cancer of the exocrine pancreas." This indicates its role in providing information for clinical decision-making regarding a patient's medical condition.
No
The device description clearly outlines physical components (Immunoreaction Cartridges, Antibody-Coated Particle Solution, Enzyme-Labeled Antibody Solution) which are chemical reagents and particles, not software. The device is an immunoassay kit used on a hardware system (LUMIPULSE G System).
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "quantitative measurement of CA 19-9 in human serum or plasma" and is used "as an aid in the management of patients diagnosed with cancer of the exocrine pancreas." This involves testing biological samples (serum or plasma) outside of the body to provide information about a patient's health status.
- Device Description: The description details the components of the "Immunoreaction Cartridges" which are used in a laboratory setting for the assay.
- Performance Studies: The description of the performance study, even though focused on interference, confirms that the device is being evaluated for its performance in analyzing biological samples.
- Predicate Device: The mention of a predicate device (K191973; Lumipulse® G CA19-9-N) indicates that this device is being compared to a previously cleared IVD.
All of these points align with the definition of an In Vitro Diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, treatment, or prevention of disease.
N/A
Intended Use / Indications for Use
Lumipulse® G CA19-9-N is a Chemiluminescent Enzyme Immunoassay (CLEIA) for the quantitative measurement of CA 19-9 in human serum or plasma (sodium heparin, lithium heparin, or dipotassium EDTA) on the LUMIPULSE G System.
The assay is to be used as an aid in the management of patients diagnosed with cancer of the exocrine pancreas who have detectable levels of CA 19-9 at some point in their disease process. Serial testing for patient CA 19-9 assay values should be used in conjunction with other clinical methods used for monitoring cancer of the exocrine pancreas.

Dear Kristin Maddaloni:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

Indications for Use
510(k) Number (if known) K200997
Device Name Lumipulse G CA19-9-N
Indications for Use (Describe)
WARNING: The concentration of CA19-9 in a given specimen, as determined by assays from different manufacturers, can vary due to differences in assay methods and reagent specificity. The results reported by the laboratory to the physician must include the identity of the assay for CA19-9 used. Values obtained with different assay methods cannot be used interchangeably. If, in the course of monitoring a patient, the assay method used for determining serial levels of CA 19-9 is changed, the laboratory must perform additional serial testing to confirm baseline values. Prior to changing assays, the laboratory MUST confirm baseline values for patients being serially monitored. Lumipulse & CA19-9-N should not be used for cancer screening or diagnosis.
WARNING: Patients known to be genotypically negative for the Lewis blood group antigen will be unable to produce the CA 19-9 antigen even in the presence of malignant tissue. Phenotyping for the presence of the Lewis antigen may be insufficient to detect true Lewis antigen negative individuals. Even patients who are genotypically positive for the Lewis antigen may produce varying levels of CA19-9 based on gene dosage effect.
Lumipulse & CA19-9-N is a Chemiluminescent Enzyme Immunoassay (CLEIA) for the quantitative measurement of CA19-9 in human serum or plasma (sodium heparin, lithium heparin, or dipotassium EDTA) on the LUMIPULSE G System.
The assay is to be used as an aid in the management of patients diagnosed with cancer of the exocrine pancreas who have detectable levels of CA19-9 at some point in their disease process.

L. TEST PRINICIPLE
Lumipulse® G CA19-9-N is an assay system, including a set of immunoassay reagents, for the quantitative measurement of CA 19-9 in human serum and plasma (sodium heparin, lithium heparin, or dipotassium EDTA) based on CLEIA technology by a two-step immunoassay method on the LUMIPULSE G1200 System. CA 19-9 in specimens specifically binds to anti-CA19-9 monoclonal antibody (mouse) on the particles, and antigenantibody immunocomplexes are formed. The particles are washed and rinsed to remove unbound materials. Alkaline phosphatase (ALP: calf)-labeled anti-CA19-9 monoclonal antibody (mouse) specifically binds to CA 19-9 of the immunocomplexes on the particles, and additional immunocomplexes are formed. The particles are washed and rinsed to

remove unbound materials. Substrate Solution is added and mixed with the particles. AMPPD contained in the Substrate Solution is dephosphorylated by the catalysis of ALP indirectly coniugated to particles. Luminescence (at a maximum wavelength of 477 nm) is generate by the cleavage reaction of dephosphorylated AMPPD. The luminescent signal reflects the amount of CA 19-9.
Indicated for the serial measurement of CA 19-9 to aid in the management of patients diagnosed with cancers of the pancreas. Serial testing with Lumipulse® G CA19-9-N for CA 19-9 patient values is used in conjunction with other clinical methods in the management of pancreatic cancer patients.
