The summary describes a chromogenic assay for measuring heparin levels, which is a standard laboratory technique. There is no mention of AI, ML, or any related computational methods for data analysis or interpretation. The performance studies focus on method comparison and precision, typical for a diagnostic assay, not on the performance of an AI/ML algorithm.
No
This device is for "in vitro diagnostic use" to measure heparin levels in human plasma, not to treat a condition.
Yes
The "Intended Use" section explicitly states, "This kit is for in vitro diagnostic use."
No
The device is a chromogenic assay kit, which is a chemical-based in vitro diagnostic (IVD) product, not a software-only medical device. It involves reagents and laboratory procedures.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "This kit is for in vitro diagnostic use."
Additionally, the "Device Description" describes a "chromogenic assay intended for the quantitative determination of unfractionated and low molecular weight heparins in human plasma," which is a typical description of an in vitro diagnostic test.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Method comparison studies versus the predicate device were performed with two lots of ACTICHROME Heparin (anti-fXa). The regression statistics in Table 1 indicate a positive correlation between the ACTICHROME Heparin (anti-fXa) assay and the predicate device.

Precision
Lot 007 precision studies evaluated intra-assay and inter-assay variability with 2 control samples run in quadruplicate over 20 runs (N = 80 per control). Lot 010 evaluated intra-assay and inter-assay variability with 2 control samples run in quadruplicate over 10 runs (N = 40 per control). Lot 010 evaluated unfractionated heparin and low molecular weight heparin. The results are provided in Tables 2a and 2b.
