The hemochroma PLUS System is for the quantitative determination of hemoglobin concentration in non-anticoagulated capillary (finger-stick) whole blood or venous whole blood (K.2-EDTA, sodium citrate, lithium heparin, or sodium heparin) of adults. The testing system is designed for point-of-care use in primary care settings, hospitals, and medical lab facilities. Estimation of hematocrit, as a function, is only for normal hemoglobin values from 12.0 to 18.0 g/ dL (120 to 180 g/L).
The hemochroma PLUS Controls are intended for use as quality control material to assure the validity and performance of the hemochroma PLUS system in measuring the human hemoglobin concentration.
The hemochroma PLUS Microcuvettes are only used with hemochroma PLUS Analyzer. This device has not been evaluated for pediatric samples. The device has been evaluated for individuals ranging in age from 18 to 96 years old. The hemochroma PLUS System is for in vitro diagnostic only.
The hemochroma PLUS Analyzer is a battery powered, hand-held device to measure the concentration of total hemoglobin in blood in 3 seconds with 15ul of whole blood. Whole blood may be collected by fingerstick (capillary) or venipuncture and analyzed without pre-processing. The hemochroma PLUS Analyzer uses hemochroma PLUS Microcuvettes with dual ports where the user applies samples either through capillary action or direct volume pipetting.
The hemochroma PLUS Analyzer determines hemoglobin concentration in whole blood samples using a dual wavelength photo-absorption method and measures the degree of light absorption with a spectrophotometer. The optical distance between the hemochroma PLUS Microcuvette walls is fixed and permits photometric determination of hemoglobin in undiluted blood samples. The computed end result is displayed on a LCD display and can be printed on an external printer (optional).
The hemochroma PLUS System consists of a hemochroma PLUS Analyzer, single-use hemochroma PLUS Microcuvettes, hemochroma PLUS ID Chip, optical System Check Microcuvette and hemochroma PLUS Controls.

hemochroma PLUS Microcuvette
The hemochroma PLUS Microcuvettes are specially designed for use with the hemochroma PLUS Analyzer. The microcuvettes function as measuring devices specifically holding 15 uL of blood and are inserted into the hemochroma PLUS Analyzer by placing it into the cuvette holder. The optical distance between the hemochroma PLUS Microcuvette walls is fixed and by measuring the degree of light absorption permits photometric determination of the hemoglobin in undiluted blood samples. -
hemochroma PLUS ID Chip
The hemochroma PLUS ID chip contains encoded memory with the calibration data/information. With the ID chip inserted in the designated port, the hemochroma PLUS Analyzer reads and utilizes the calibration data regarding the lot under consideration and applies appropriate correction to the conversion formula while computing the test result. -
hemochroma PLUS Optical System Check Microcuvette
hemochroma PLUS Optical System Check Microcuvette is designed for use with the hemochroma PLUS Analyzer only. The Optical System Check Microcuvette is a special glass filter used to measure the degree of light absorption with the spectrophotometric method. If the result is between 11.7-12.3 g/dL, the optic system is working properly according to specification. -
hemochroma PLUS Controls
The hemochroma PLUS Controls: Level 1 (Low), Level 2 (Middle), and Level 3 (High), are external quality controls designed for use with hemochroma PLUS Analyzer only.
Here's an analysis of the provided text, focusing on the acceptance criteria and study proving the device's performance:
The document is a 510(k) Summary for the "hemochroma PLUS System," an automated hemoglobin system. It outlines the analytical performance studies conducted to establish substantial equivalence to a predicate device.
Acceptance Criteria and Reported Device Performance
The document doesn't explicitly list "acceptance criteria" for each study in a table format. Instead, it states for each analytical study that the "results were within the defined acceptance criteria" or "met the acceptance criteria." This implies that internal acceptance criteria were pre-established by the manufacturer for each test (e.g., repeatability, reproducibility, linearity, interference, method comparison, stability, detection limits) and the observed performance successfully satisfied them.
However, based on the provided results, we can infer some performance metrics:
| Study/Parameter | Acceptance Criteria (Inferred) | Reported Device Performance |
|---|---|---|
| Repeatability (CV%) | Not explicitly stated; implied to be acceptable for various Hb levels. | Within Run %CV: |

(a)
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.(b)
Classification. Class II (performance standards).
