Intended Use
The GDS® HemoSite® Test System is a device for in vitro diagnostic use only. The GDS® HemoSite® Test Card is intended for the quantitative determination of hemoglobin in whole blood. It is intended for use with the Stat-Site® Meter.
Device Description
The HemoSite® Test Cards are dry-chemistry Test Cards that contain chemicals which react and produce color when hemoglobin is present. The Stat-Site® Meter is a reflectance colorimeter that reads color intensity. A Test Module is provided with each box of Test Cards. The Test-Module contains all current calibration information for the specific lot of reagent. The Test Module and Test Cards are coded to each other, and the Stat-Site® Meter will only operate if they are properly matched. HemoSite® Test Cards are dry reagent cards based on the azidemethemoglobin method. When a drop of whole blood is applied to the top of the Test Card, hemolysis occurs, with the release of hemoglobin. Sodium nitrite converts the hemoglobin to methemoglobin. Sodium azide converts methemoglobin to azidemethemoglobin to produce a brown color that is measured at 580 nm using the Stat-Site® Meter. The Stat-Site® Meter measures the color intensity and calculates the hemoglobin concentration.
More Information

No
The device description details a dry-chemistry method and a reflectance colorimeter. The calculation of hemoglobin concentration is based on color intensity measurement, which is a standard photometric technique and does not indicate the use of AI/ML. There is no mention of AI, ML, or related terms in the document.

No
The device is described as an "in vitro diagnostic device only" and is used for "quantitative determination of hemoglobin in whole blood." It does not provide any treatment or therapy to a patient.

Yes

The device is explicitly stated as being for "in vitro diagnostic use only" in the "Intended Use / Indications for Use" section. It quantifies hemoglobin, which is a diagnostic measurement.

No

The device description clearly outlines hardware components: HemoSite® Test Cards (dry-chemistry), a Stat-Site® Meter (reflectance colorimeter), and a Test Module. The software component is part of the Stat-Site® Meter's function to measure color intensity and calculate hemoglobin concentration, but it is integrated with and dependent on the hardware.

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

The document explicitly states in the "Intended Use / Indications for Use" section: "The GDS® HemoSite® Test System is a device for in vitro diagnostic use only." This statement directly identifies the device as an IVD.

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

Comparison:
To verify safety and effectiveness of the Stat-Site®/HemoSite® Hemoglobin Test when used under intended use conditions such as a POL setting, the device was compared with the Coulter® JT hematology analyzer. A total of 212 venous and capillary blood samples were obtained internally and at three different physician's office sites. HemoSite® Test System results were compared to the venous blood results from the Coulter® JT reference method. The following regression statistics were obtained: Venous Blood: Y = 0.90x + 1.3, r=0.8878 Capillary Blood: Y = 1.0x - 0.18. r=0.8358

Precision evaluation was performed with whole blood hemoglobin concentrations of 8.7, 13.8 and 18.9 g/dL. All whole blood within-run precision estimates were below 4 %CV. Total precision estimates ranged from 3.0-3.5 %CV at high hemoglobin levels. 5.7-5.9 %CV at normal levels, and 5.9-7.2 %CV at low hemoglobin levels.

Conclusion:
The data demonstrates that blood hemoglobin results from the Stat-Site®/HemoSite® Test System, when used in a point of care setting such as a POL or physician's office, compare well to those of laboratory instruments such as the Coulter® JT when determining blood hemoglobin concentrations.
