The G5 I HbA₁c assay is intended for use in a physicians/doctors office. The assay is not intended for use as a home use or for self-testing. The G5 II HbA1c assay is an affinity chromatography method and is intended for the in-vitro quantitative determination of HbA1c in capillary blood taken from a finger prick. The test is indicated for use by diabetics for monitoring the time averaged blood glucose levels of known diabetics as an indicator of overall glycaemic control. The G5 II HbA1c assay is intended for use as a prescription home use test.
Device Description

More Information

Not Found

No
The description focuses on affinity chromatography and standard laboratory performance metrics, with no mention of AI/ML terms or methodologies.

No
The device is an in-vitro diagnostic test intended for quantitative determination of HbA₁c to monitor blood glucose levels in diabetics, not to treat a condition.

Yes

The device is intended for the quantitative determination of HbA1c, which is used by diabetics for monitoring blood glucose levels. This determination provides information crucial for the diagnosis and management of the disease, fitting the definition of a diagnostic device.

No

The device description explicitly states it is an "Instrument read, single use in vitro test," indicating it involves physical components (test cartridges and a reader instrument) in addition to any potential software for data processing or display.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The document explicitly states the intended use is for the "in-vitro quantitative determination of HbA₁c". "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs. It also specifies the sample type (blood) and the purpose (monitoring blood glucose levels in diabetics).
  • Device Description: The description clearly labels it as an "in vitro test".
  • Sample Type: The device uses blood samples (capillary or whole blood), which are biological specimens tested outside the body.

These points align directly with the definition of an In Vitro Diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or treatment.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical Studies:
Clinical trial carried out at Southport DGH, UK to evaluate a rapid blood test for the measurement of Glycated protein in subjects with type I and type II diabetes mellitus. The data from 74 patients demonstrated that the G5 HbAre assay is substantially equivalent to the Glycosal assay with a correlation coefficient of 0.96 for fresh finger prick and 0.97 for stored EDTA blood.

POL Studies (G5 I):
Evaluation of the G5 HbAie test using non-laboratory participants. Three separate Physician Office Laboratory (POL) studies were carried out. Each consisting of 5 standards run in triplicate and at least 20 blood samples (EDTA stored blood and/or fresh finger prick) run by a trained operator and an untrained operator. Each site produced acceptable data for accuracy and precision, with correlation coefficients of >0.95. accuracy within ± 10% and CV less than 4.6%.

Home Use - Consumer Study (G5 II):
This study took place at 3 separate sites in the USA and compared untrained subjects to trained subjects. The untrained subjects using only the supplied packaging achieved acceptable correlation to the trained operators.

Non Clinical Laboratory Studies:

  • Assessing the linearity of the G5 HbAir assay: A study was conducted to prove the G5 HbA1c is linear over the assay range. Results demonstrated that the assay is linear between 6 and 14% HbAIc.
  • The effect of Haemoglobinopathies on the G5 HbA1c assay: This validation is covered by reference WG John. Glycated haemoglobin analysis. Ann Clin Biochem 1997; 34: 17-31. Boronate methodology is not affected by HbS, HbC. HbF or by high levels of carbamylated haemoglobin in Uremic patients.
  • The Effect of Abnormal blood chemistries upon the accuracy of the GS HbA1c assay: The effect of abnormal blood chemistries, i e. raised lipids and raised bilirubin upon the determination of %HbAir needed to be investigated. Triglycerides up to 4.0 mmol/L and Bilirubin up to 345 umol/L do not affect the test result.
  • The Effect of Interfering Drugs upon Accuracy of the G5 HbA1c assay: The effect of the commonly prescribed pharmaceutical drugs (aspirin, paracetemol, caffeine and anti-histamine) upon the performance of the G5 HbA1c test needed to be assessed. None of the listed compounds affected the HbA1c test result.
  • Investigating the effect of labile HbA1c on the G5 HbA1c assay: This validation is covered by reference WG John. Glycated haemoglobin analysis. Ann Clin Biochem 1997: 34: 17-31. Boronate Methodology is not affected by Labile HbAic:
  • Investigating the analysis of variance of reproducibility of the G5 HbA1c assay: A study was performed to investigate the analysis of variance of reproducibility of the G5 HbA1c assay. Using a normal and an abnormal control, which were assayed in duplicate twice during each day over a period of 20 days, it was demonstrated that the variance was acceptable, with an overall CV precision of less than 5%.
  • Investigating the assay reproducibility (Inter batch variation) of the G5 HbA1c ASSAY: A study was performed to determine the intra and inter batch variation of the G5 HbAic assay. Using 3 %HbAic standards on 3 batches of G5 devices it was demonstrated that the G5 assay was acceptable in terms of repeatability and reproducibility with assay %CV's of less than 5%.
  • Investigation into the use of stored blood for the G5 HbAic assay: It was demonstrated that the assay can be run acceptably with fresh finger prick, EDT A blood for up to 4 days after collection when the blood is stored at 2-8°C.
  • Investigating the effect of Total Haemoglobin and Haematocrit on the G5 HDAit ASSAV: Results demonstrated that the assay performs acceptably within a haemoglobin range of 11-18g/dl and a haematocrit range of 35% to 55%.
  • G5 HbA1c test cartridge stability: Results demonstrated that the assav is stable for at least 12 months at 2-8°C.
  • Assessing the time required to equilibrate the G5 device to room temperature from 2-8°C: The results demonstrated that the minimum time required for equilibration is 2 hours.
  • Assessing the acceptable time a device can be left after sample addition prior to insertion into the G5 reader: The results demonstrated that the device needed to be inserted immediately after sample addition.

§ 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).
