The ACCU-CHEK Aviva Expert System is indicated as an aid in the treatment of insulin-requiring diabetes. The ACCU-CHEK Aviva Expert System consists of the ACCU-CHEK Aviva Expert Meter, ACCU-CHEK Aviva Plus test strips, ACCU-CHEK Aviva control solutions, and ACCU-CHEK Bolus Advisor. The ACCU-CHEK Aviva Expert System is intended to facilitate the optimization of glycemic control in multiple daily insulin injection therapy and are under the supervision of healthcare professionals experienced in managing insulin treated patients. The ACCU-CHEK Aviva Expert blood glucose monitoring system is intended to be used for the quantitative measurement of glucose in fresh capillary whole blood samples drawn from the fingertips. The ACCU-CHEK Aviva Expert blood glucose monitoring system is intended for self-testing outside the body (in vitro diagnostic use) by people with diabetes. The ACCU-CHEK Aviva Expert blood glucose monitoring system is intended to be used by a single person and should not be shared. The ACCU-CHEK Aviva Expert blood glucose monitoring system should not be used for the diagnosis or screening of diabetes or for neonatal use. Alternative site testing should NOT be used with the ACCU-CHEK Aviva Expert blood glucose monitoring system. The ACCU-CHEK Aviva Expert System is intended for prescription home use only.

The ACCU-CHEK Aviva Expert meter is also indicated for the calculation of an insulin dose or carbohydrate intake based on user-entered data. The ACCU-CHEK Bolus Advisor, as a component of the Accu-Chek Aviva Expert meter, is intended for use in providing insulin dose recommendations in response to blood glucose, health events, and carbohydrate input. The ACCU-CHEK Bolus Advisor is intended to provide direction for insulin adjustment within the scope of a preplanned treatment program from a healthcare professional. Before its use, a physician or healthcare professional must prescribe the ACCU-CHEK Aviva Expert System and provide the patient-specific target blood glucose, insulin-to-carbohydrate ratio, and insulin sensitivity parameters to be programmed into the ACCU-CHEK Bolus Advisor. Once programmed, a patient must consult with his/her physician or healthcare professional before making any changes to these ACCU-CHEK Bolus Advisor settings.

The ACCU-CHEK Aviva Expert System consists of the following which was originally cleared under K131366:

• ACCU-CHEK Aviva Expert meter
• ACCU-CHEK Bolus Advisor (a component of the Aviva Expert meter)
• ACCU-CHEK Aviva Plus test strips
• ACCU-CHEK Aviva control solutions

The ACCU-CHEK Aviva Expert system is a blood glucose monitoring system that makes use of the ACCU-CHEK Aviva Plus test strips and the ACCU-CHEK Aviva control solutions.

The ACCU-CHEK Aviva Expert system provides the user with the ability to measure capillary blood glucose levels when a sample of capillary blood is applied to the test strip. The meter also provides an optional insulin bolus calculator (the ACCU-CHEK Bolus Advisor) designed for use by individuals with diabetes who require insulin. This feature is optional in that a user can simply obtain a blood glucose value through capillary blood testing and does not need to use the insulin bolus calculator portion of the system if it is not desired. For the ACCU-CHEK Aviva Expert system, this bolus calculator is meant to be used by patients with diabetes on multiple daily insulin injection (MDI) therapy. In order to calculate the appropriate bolus of insulin, the ACCU-CHEK Bolus Advisor takes the measured bG, the target bG, the carbohydrate intake, the insulin-to-carbohydrate ratio, the insulin sensitivity, health events (such as exercise), the time of day, and the active insulin into account. Before using the ACCU-CHEK Aviva Expert system, a physician or healthcare professional must provide the patient-specific target blood glucose, insulin-to-carbohydrate ration, and insulin sensitivity parameters.

Here's a breakdown of the acceptance criteria and study information based on the provided text, focusing on the performance of the ACCU-CHEK Aviva Expert Blood Glucose Monitoring system:

The document describes the ACCU-CHEK Aviva Expert Blood Glucose Monitoring system and refers to performance testing that was submitted and cleared under a previous 510(k) (K131366). The current submission (K142089) states that "The ACCU-CHEK® Aviva Expert System has not changed since this prior submission and the information submitted here is provided to support the clarification in the intended use statement." Therefore, the performance data presented is for the identical device.

1. Table of Acceptance Criteria and Reported Device Performance

The provided document presents performance data as evidence of the device meeting requirements for its intended use, but does not explicitly state predetermined "acceptance criteria" as separate rows. However, to construct a table, we can infer the acceptance criteria from the reported results, assuming the reported values met the relevant regulatory standards for blood glucose monitoring systems at the time of clearance.
