K991385 (The given text has only Predicate Device, not Reference Device)
No
The device description details a standard ELISA assay, which relies on chemical reactions and optical density measurements, not AI/ML algorithms for analysis or interpretation. The "Mentions AI, DNN, or ML" field is also explicitly marked as "Not Found".
No
This device is an in vitro diagnostic (IVD) tool designed to measure C-reactive protein (CRP) levels to aid in evaluating body tissue injury, not to provide therapeutic treatment.
Yes
The text explicitly states: "The Wampole™ HS-CRP ELISA is a Class II in vitro medical diagnostic device".
No
The device description clearly outlines a physical ELISA kit with reagents, microwell strips, and a requirement for an ELISA reader, indicating it is a hardware-based in vitro diagnostic device, not software-only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The description explicitly states it is an "in vitro diagnostic enzyme-linked immunosorbent assay (ELISA) intended for the quantitative measurement of C-reactive protein (CRP) levels in human serum and plasma." This directly aligns with the definition of an IVD, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a laboratory test that analyzes biological samples (serum and plasma) using chemical reactions (ELISA) to measure a specific substance (CRP). This is characteristic of an IVD.
- Class II in vitro medical diagnostic device: The device description explicitly labels it as a "Class II in vitro medical diagnostic device." This is a regulatory classification specifically for IVDs.
The information provided clearly indicates that this device is designed to be used outside of the body to analyze human specimens for diagnostic purposes, which is the core function of an IVD.

Device Description
The Wampole™ HS-CRP ELISA is a Class II in vitro medical diagnostic device that utilizes conventional enzyme-linked immunosorbent assay technology to quantitatively measure the level of C-reactive protein (CRP) in a serum or plasma specimen.
The assay kit consists of plastic microwell strips, containing adsorbed monoclonal anti-CRP antibody. CRP in the specimen is captured by the immobilized antibody, forming immobilized immune complexes. After washing away excess specimen, polyclonal anti-CRP antibody that has been conjugated to horseradish peroxidase is added, forming a "sandwich" of monoclonal antibody, CRP antigen, and conjugated polyclonal antibody. After washing, the immobilized CRP sandwich is exposed to tetremethlybenzidine (TMB), a chromogenic substrate that turns from clear to blue in the presence of peroxidase reaction products. The peroxidase reaction is stopped by the addition of dilute sulfuric acid, which also changes the color of the solution from blue to yellow. The optical density of the yellow end product is directly proportional to the amount of bound CRP antigen, and is quantitated on an ELISA reader at 450 nm. Specimen CRP levels are then determined by interpolation from a standard curve of optical density versus CRP concentration.

II. 510(k) SUMMARY (cont'd)
Intended Use of the Device:
The Wampole HS-CRP ELISA is an in vitro diagnostic enzyme-linked immunosorbent assay (ELISA) intended for the quantitative measurement of C-reactive protein (CRP) levels in human serum and plasma. CRP measurements aid in the evaluation of the extent of injury to body tissues.
Technological Characteristics:
The Wampole HS-CRP ELISA uses conventional "microwell" technology, is similar in technology to other "sandwich" ELISA devices and it has the same characteristics and intended use as the predicate device. Other devices include those that detect circulating levels of lipoproteins or human chorionic gonadotropin (hCG). The Wampole HS-CRP ELISA has the same technological features, characteristics and intended use as the predicate device. The monoclonal and polyclonal antibodies used, as well as the recombinant standard antigen, all are derived from established technology. The colored end product is read on standard ELISA readers, which use monochromatic filters of wavelengths pre-selected for specific substrates.
