## Indications for Use

The HemoPoint H2 Hemoglobin Measurement System is indicated for the quantitative determination of hemoglobin in arterial, venous, or capillary whole blood of adults, infants, and children in a professional point-of-care setting. The microcuvettes part number 3010-100 is indicated for use in the Hemopoint® H2 Hemoglobin Measurement System and HemoCue® B-Hemoglobin Photometer.

## Device Story

System consists of HemoPoint H2 photometer and disposable microcuvettes; used in professional point-of-care settings. Blood sample loaded into microcuvette via capillary action; cuvette inserted into photometer. Device utilizes modified azide methemoglobin (Vanzetti) method to measure color reaction; results displayed via LED readout. Includes time/data logging and storage capabilities. Provides rapid hemoglobin quantification to assist clinicians in diagnostic decision-making.

## Clinical Evidence

Clinical studies across 4 sites compared the HemoPoint H2 to the NCCLS H15-A3 reference method and the HemoCue system. Correlation coefficients were >0.98 against the reference method and ≥0.97 against the HemoCue system. Precision testing (NCCLS EP5-A) showed within-run CVs ≤0.9% and total precision CVs ≤1.2% across high, low, and normal hemoglobin ranges.

## Technological Characteristics

Photometric system using LEDs at 570 nm and 880 nm. Employs azide methemoglobin method for hemoglobin determination. Measures light transmission through undiluted blood in microcuvettes. Provides results in g/dL, g/L, or mol/L. Measurement time 30-60 seconds.

## Regulatory Identification

An automated hemoglobin system is a fully automated or semi-automated device which may or may not be part of a larger system. The generic type of device consists of the reagents, calibrators, controls, and instrumentation used to determine the hemoglobin content of human blood.

## Predicate Devices

- HemoCue B-Hemoglobin System

K. Test Principle:
The device uses a modified azide methemoglobin method (Vanzetti) to measure hemoglobin.

A small amount of blood is loaded into the microcuvette via capillary action. The cuvette is then inserted into the HemoPoint H2 photometer where the color produced by the chemical reaction in the cuvette is measured. Results are displayed by LED readout.
