The document describes standard optical signal analysis algorithms and does not mention AI or ML.
No
The device is an in-vitro diagnostic system used to measure % HbA1c, which is a diagnostic and monitoring tool, not a therapeutic intervention.
Yes
The device is intended for "quantitative measurement of % HbA1c (DCCT/NGSP) and mmol/mol HbA1c (IFCC) in human anticoagulated venous whole blood" for "in-vitro diagnostic use by healthcare professionals."
No
The device description clearly states the system includes hardware components: the Aina 2 Automated HbA1c Device, the Aina Device (a reflectance-based colorimetric sensor device), and Aina HbA1c Test Kits. While the Aina Mobile Application is software, it is part of a larger system that relies on physical hardware for sample processing, optical readout, and reagent delivery.
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 by healthcare professionals in a laboratory environment..."
- Measurement of Biomarkers: The system is designed for the "quantitative measurement of % HbA1c (DCCT/NGSP) and mmol/mol HbA1c (IFCC) in human anticoagulated venous whole blood." HbA1c is a biomarker measured in a biological sample (blood) to provide information about a person's health status (long term glycemic control).
- Sample Type: It uses "human anticoagulated venous whole blood," which is a biological specimen.
- Purpose: The purpose is to "monitor long term glycemic control of persons previously diagnosed with diabetes," which is a diagnostic purpose.
All of these points align with the definition of an In Vitro Diagnostic device, which is a medical device intended for use in vitro for the examination of specimens derived from the human body solely or principally for the purpose of providing information concerning a physiological or pathological state, or a congenital abnormality, or to determine the compatibility of tissues or organs, or to monitor therapeutic measures.

which is software that allows for user interaction and illustrates the step-by-step testing process on its touchscreen. The Aina Mobile Application software is responsible for analyzing the optical signals measured by and transferred to it by the Aina Device, including applying analysis algorithms to compute the HbA1c reading. In addition, the Aina Mobile Application controls the functioning of the Aina 2 Automated HbA1c Device by sending it commands via Bluetooth. Streck A1c-Cellular control solutions can be used for regular quality control checking of the system.
Methodology
The Aina HbA1c Test utilizes the boronate affinity method. The Aina HbA1c Test Kit consists of test strips, reagents, wash buffers, capillary tubes for sample collection, and pipette tips. The reagent contains a lysing agent and a blue boronic acid conjugate. When blood is added to the reagent, the erythrocytes are lysed and all hemoglobin precipitates. The boronic acid conjugates binds to the glycosylated hemoglobin. An aliquot of the reaction mixture is applied to the test strip and all the precipitated hemoglobin, conjugate-bound and unbound, remains on top of the filter. Any unbound boronate is removed with the wash buffer. The precipitate is evaluated by measuring the blue (glycosylated hemoglobin) and the red (total hemoglobin) color intensity respectively with the Aina Device, the ratio between them being proportional to the percentage of the glycosylated hemoglobin in the sample.
Limitations of the Test
- The allowed operating temperature range is 18 to 40°C (64 to 104°F). The recommended range is 20 to 25°C (68 to 77°F)
- The Aina HbA1c Monitoring System 2 is intended to be used at altitudes of up to 2000 meters (6562 feet). The HbA1c readings may be affected at an altitude above 2000 meters (6562 feet).
- The reagent and wash buffer must be stored in the designated temperature range (2 to 8°C). Test results may be inaccurate if they are stored outside of this temperature range for more than 2 hours.
- Do not use the reagent and wash buffer if kept at room temperature for more than 2 hours.
- · Use only fresh venous whole blood. Do not use serum or plasma.
- · The Aina HbA1c Monitoring System 2 is not intended for point-of-care use.
- This test should not be used in monitoring daily glucose control and should not be used to replace daily home testing of urine and blood glucose levels.
- This test is not intended for use in the diagnosis of or screening for diabetes.
- This test is not intended for use on neonates.
- This test should not be used for analyzing samples from patients with conditions causing shortened red blood cell survival, such as hemolytic diseases, pregnancy and significant acute or chronic blood loss.
- Hemoglobinopathies may interfere with glycated hemoglobin analysis. The results from the Aina HbA1c Monitoring System 2 show that there is no significant interference for samples containing Hemoglobin C (≤ 50%), Hemoglobin D (≤ 43%), Hemoglobin E (≤ 31%), Hemoglobin S (≤ 42%), and Hemoglobin A2 (≤ 6.5%).

- Acetylated, carbamylated, and labile-glycated hemoglobin derivatives generated with normal and diabetic specimens by incubation with acetylsalicylic acid, sodium cyanate, and glucose at concentrations up to 126.1, 32.5, and 1000 mg/dL respectively do not interfere with the assay.
- Samples with a hemoglobin concentration lower than 7.2 g/dL or higher than 20 g/dL can cause inaccurate test results.
WARNING: The Aina HbA1c assay has significant negative interference from Hemoglobin F (HbF). HbA1c results are invalid for patients with abnormal amounts of HbF, including those with known Hereditary Persistence of Fetal Hemoglobin.

Hemoglobin Variants
The objective of this study was to evaluate the interference effect of hemoglobin variants, as found in patients with natural hemoglobinopathies, in the quantitative measurement of HbA1c using the Aina system on venous whole blood samples.
The results from the Aina HbA1c Monitoring System 2 show that there is no significant interference for samples containing Hemoglobin C (≤50%), Hemoglobin D (≤43%), Hemoglobin E (≤31%), Hemoglobin S (≤ 42%), and Hemoglobin A2 (≤ 6.5%).
WARNING: The Aina HbA1c assay has significant negative interference from Hemoglobin F (HbF). HbA1c results are invalid for patients with abnormal amounts of HbF, including those with known Hereditary Persistence of Fetal Hemoglobin.

Performance Data: Clinical Studies
To demonstrate accuracy of the system, fresh prospective venous whole blood was collected with K₂-EDTA as an anticoagulant from study participants at three (3) clinical sites and then tested on the Aina HbA1c Monitoring System 2 by trained healthcare professionals in a laboratory environment. Clinical performance of the Aina HbA1c Monitoring System 2 was compared to the Tosoh G8 reference method. Regression analysis (n=132) was performed to compare the results from the Aina HbA1c Monitoring System 2 to the Tosoh G8 using both Passing-Bablok and Weighted Deming analysis.
