The summary describes a laboratory assay and associated reagents for measuring tryptase levels. There is no mention of AI or ML in the intended use, device description, or performance studies. The device is a traditional in vitro diagnostic assay.
No
This device is an in vitro diagnostic assay used for measurement of tryptase levels, which aids in diagnosis rather than actively treating a condition.
Yes
The document states that the device is "intended for in vitro diagnostic use as an aid in the clinical diagnosis of patients with a suspicion of systemic mastocytosis".
No
The device description explicitly lists physical reagents (ImmunoCAP Tryptase reagents, calibrators, controls, etc.) which are hardware components used in the in vitro diagnostic assay.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states: "It is intended for in vitro diagnostic use as an aid in the clinical diagnosis of patients with a suspicion of systemic mastocytosis..."
- Device Description: The description details reagents used to perform an assay on human serum or plasma, which are biological samples tested in vitro (outside the body).
- Performance Studies: The document describes clinical performance studies using patient samples to verify the device's effectiveness in aiding diagnosis.
- Predicate Device: The mention of a "Predicate Device(s)" with a K number (K103039) indicates a regulatory submission process typical for IVDs.
All these points strongly support the classification of this device as an In Vitro Diagnostic.

Device Description
ImmunoCAP Tryptase reagents are modular in concept and are available individually in different package sizes dependent on instrument system used.
The reagents needed to perform the ImmunoCAP Tryptase assay are listed below.

Phadia 100 and Phadia 250 instruments with associated software process all steps of the assay and calculate results automatically after the assay is completed.
Test Principle, ImmunoCAP Tryptase: Anti-tryptase, covalently coupled to ImmunoCAP, reacts with the tryptase in the patient sample. After washing, enzyme labeled antibodies against tryptase are added to form a complex. After incubation, unbound enzyme-anti-tryptase is washed away and the bound complex is then incubated with a developing agent. After stopping the reaction, the fluorescence of the eluate is measured. The higher the response value, the more tryptase is present in the sample. To evaluate the test results, the responses of the patient samples are transformed into concentrations with the use of a calibration curve.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The updated ImmunoCAP Tryptase was compared with the currently cleared ImmunoCAP Tryptase with the use of samples with and without clinical documentation, as well as samples from healthy individuals. The analytical performance characteristics of the updated ImmunoCAP Tryptase were verified through studies of precision, lot-to-lot reproducibility, linearity, limit of detection, hook, analytical specificity, interference of HAMA, recovery and sample matrix.
The clinical performance was verified through studies performed at two sites, including in total 138 patients with a suspicion of systemic mastocytosis. The results showed that the clinical performance of ImmunoCAP Tryptase has not changed when used as an aid in the routine clinical diagnosis of systemic mastocytosis according to WHO criteria.

Traditional 510(k) Submission, Update of ImmunoCAP Tryptase A.6 510k Summary
The clinical performance was verified through studies performed at two sites, including in total 138 patients with a suspicion of systemic mastocytosis. The results showed that the clinical performance of ImmunoCAP Tryptase has not changed when used as an aid in the routine clinical diagnosis of systemic mastocytosis according to WHO criteria.
Conclusion
The analytical and clinical data included in this 510(k) submission support that the updated ImmunoCAP Tryptase is substantially equivalent to the currently cleared product.
