The summary describes a standard in vitro diagnostic assay for measuring cholinesterase levels and does not mention any AI or ML components in its description, intended use, or performance studies.
No.
The device is an in vitro diagnostic assay used to measure cholinesterase for diagnosis and treatment of conditions, but it does not directly treat or provide therapy to a patient.
Yes
The "Intended Use / Indications for Use" section explicitly states, "Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition and disorders."
No
The device is described as an "in vitro diagnostic assay" and a "liquid assay," indicating it is a chemical reagent or kit used to perform a test, which is a physical product, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "For In Vitro diagnostics use only."
- Device Description: The "Device Description" section also explicitly states: "Sentinel Cholinesterase Liquid is an in vitro diagnostic assay..."
- Regulatory Classification: The "Intended Use / Indications for Use" section references "CFR 862.3240", which is the Code of Federal Regulations section for Cholinesterase test systems, a type of in vitro diagnostic device.
- Purpose: The device is used to measure a substance (cholinesterase) in human specimens (serum and plasma) for the purpose of diagnosis and treatment. This is the core function of an IVD.

Intended Use / Indications for Use
The Sentinel Cholinesterase Liquid assay is used to measure cholinesterase in human specimens. There are two principal type of cholinesterase in human tissues. True cholinesterase is present at nerve endings and in erythrocytes but is not present in plasma. Pseudo cholinesterase is present in plasma and liver but is note present in erythrocytes. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition and disorders. For In Vitro diagnostics use only.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative performance studies were conducted using the AEROSET System and the ARCHITECT c 8000 System. For the AEROSET System, the modified Sentinel Cholinesterase Liquid assay method comparison yielded acceptable correlation with the Sentinel Cholinesterase Liquid Model Number 17.019A and 17.606 assay on Hitachi 717. For the ARCHITECT c8000 system, the modified Sentinel Cholinesterase Liquid assay method comparison yielded acceptable with the modified Sentinel Cholinesterase Liquid on the AEROSET system. These data demonstrate the performance of the modified Sentinel Cholinesterase Liquid assay is substantially equivalent to the performance of the cleared Sentinel Cholinesterase Liquid Model Number 17.019A and 17.606.

§ 862.3240 Cholinesterase test system.
(a)
Identification. A cholinesterase test system is a device intended to measure cholinesterase (an enzyme that catalyzes the hydrolysis of acetylcholine to choline) in human specimens. There are two principal types of cholinesterase in human tissues. True cholinesterase is present at nerve endings and in erythrocytes (red blood cells) but is not present in plasma. Pseudo cholinesterase is present in plasma and liver but is not present in erythrocytes. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition disorders (e.g., insecticide poisoning and succinylcholine poisoning).(b)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.
The assigned 510(k) number is: K051444
Test Description:
Sentinel Cholinesterase Liquid is an in vitro diagnostic assay for the quantitative determination of cholinesterase in serum and plasma.
Substantial Equivalence:
The modified Sentinel Cholinesterase Liquid assay is substantially equivalent to the cleared Sentinel Cholinesterase Liquid Model Number 17.019A and 17.606 assay on Hitachi 717 (K981800). The modifications consisted of the adaptation of the general purpose Sentinel Cholinesterase Liquid Model Number 17.019A and 17.606 assay to be used on the Abbott AEROSET® and the ARCHITECT® c8000® Analyzers. This (these) modifications did not significantly change the safety and effectiveness of the device as demonstrated in the Performance Characteristics Summary.
