The summary describes a sample collection kit and its performance in collecting blood samples for laboratory analysis. There is no mention of AI or ML being used in the collection process or the subsequent laboratory analysis described.
No.
This device is a sample collection kit for in vitro diagnostic laboratory evaluation of HbA1c to monitor long-term blood glucose control. It does not directly treat or prevent a disease, injury, or condition.
Yes
The device is intended for in vitro diagnostic laboratory evaluation and to monitor long-term blood glucose control in patients with diabetes mellitus. While it's noted that it's not for the diagnosis of diabetes, its use for monitoring a medical condition classifies it as a diagnostic device.
No
The device description explicitly lists physical components such as a lancet, alcohol pad, gauze pad, bandage, mailing envelope, and a blood sample collection card, indicating it is a hardware-based sample collection kit, not software only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the kit is for the "collection of a capillary blood sample on a blood sample collection card for in vitro diagnostic laboratory evaluation of the amount of HbA1c". The phrase "in vitro diagnostic laboratory evaluation" is a key indicator of an IVD.
- Purpose: The device is used to collect a sample that will be analyzed outside of the body (in vitro) to provide diagnostic information (monitoring long-term blood glucose control in patients with diabetes mellitus).
- Device Description: The description confirms that the collected sample is sent to a clinical laboratory for the determination of percent hemoglobin A1c, which is a diagnostic measurement.
While the kit itself is a sample collection device, its intended purpose is solely to facilitate an in vitro diagnostic test performed in a laboratory. Therefore, it falls under the definition of an IVD.

Summary of Performance Studies
Performance studies were conducted on blood samples collected with Precision A1c cards by both lay users and trained operators at three sites. A corresponding venous whole blood sample was also collected from each patient in the study as a control sample to compare whole blood results to those obtained from blood samples collected with the Precision A1c card. Samples from two clinical sites were then mailed to LabOne for determination of percent glycohemoglobin. Samples collected by the University of Missouri were not mailed but were tested on-site.
Performance studies included:
-Correlation of %HbA1c values obtained with whole blood vs. samples collected on the Precision A1c card by trained operators.
-Correlation of %HbA1c values obtained with whole blood vs. samples collected on the Precision A1c card by lay users.
-Correlation of %HbA1c values obtained by trained operators vs. lay users on samples collected with the Precision A1c card.
The performance results from all sites combined are described below:
- Trained Operator using the Precision A1c Sample Collection Kit vs. Whole Blood: Correlation Coefficient 0.993, Slope 1.019, y-Intercept -0.02, Sy.x 0.22, Bias 0.12, Mean Absolute % Bias 2.50, N 258
- Lay User using the Precision A1c Sample Collection Kit vs. Whole Blood: Correlation Coefficient 0.989, Slope 1.016, y-Intercept -0.05, Sy.x 0.27, Bias 0.07, Mean Absolute % Bias 2.77, N 259
- Trained Operator vs. Lay User-both using the Precision A1c Sample Collection Kit: Correlation Coefficient 0.996, Slope 0.999, y-Intercept -0.04, Sy.x 0.18, Bias -0.05, Mean Absolute % Bias 1.76, N 259
Conclusion: Both the correlation coefficients and slopes obtained in this study were close to 1.000 and the y-intercepts close to 0.0. Results indicate excellent correlation between venous whole blood samples and capillary blood samples (collected with the Precision A1c Kit) and analyzed by the Roche Cobas Systems. In addition, equivalent results were achieved by lay users and trained operators when compared against each other.

§ 864.7470 Glycosylated hemoglobin assay.
(a)
Identification. A glycosylated hemoglobin assay is a device used to measure the glycosylated hemoglobins (A1a , A1b , and A1c ) in a patient's blood by a column chromatographic procedure. Measurement of glycosylated hemoglobin is used to assess the level of control of a patient's diabetes and to determine the proper insulin dosage for a patient. Elevated levels of glycosylated hemoglobin indicate uncontrolled diabetes in a patient.(b)
Classification. Class II (performance standards).
