Trade Name: DiaSpect Hemoglobin T and DiaSpect Hemoglobin Cuvettes
Classification Name: Automated Hemoglobin System
Device Product Code: GKR
Predicate Device: HemoCue Hb 301 Hb and HemoCue Hb 301 Microcuvettes (K060048)
The DiaSpect Hemoglobin T system is designed for quantitative total hemoglobin determination in human blood donation settings, using capillary or venous samples in a specially designed analyzer, the DiaSpect Hemoglobin T analyzer,with specially designed, disposable microcuvettes, DiaSpect Hemoglobin Cuvettes. The Diaspect Hemoglobin T analyzer is only to be used with Diaspect Hemoglobin Cuvettes. For in vitro diagnostic use only.
The Diaspect Hemoglobin T is a single analyte instrument, for use with DiaSpect Hemoglobin Cuvettes, which has self-contained features to perform direct measurement and readout without reagents.
The instrument is a spectrophotometric analyzer for the measurement of total hemoglobin concentration in unaltered human blood. In order to determine the hemoglobin level in a sample of human blood, the cuvette draws a small amount (approximately 10μL) of venous or capillary blood by capillary effect. The user places the filled cuvette in the motor-driven drawer of the DiaSpect Hemoglobin T. The hemoglobin level is determined automatically and appears in the display after a brief measuring time of about 1 second.
The DiaSpect Hemoglobin Cuvette is injection-molded of optical plastic (PMMA) and contains a cavity volume of approximately10 μl. The optical window permits photometric determination of hemoglobin in undiluted and unaltered blood. The cuvette does not contain any reagents. The DiaSpect Hemoglobin Cuvettes are intended as single use and must be disposed of immediately after sampling in accordance with local regulations for potentially infectious waste.
Comparison Table with Predicate Device:
The DiaSpect Hemoglobin T and DiaSpect Hemoglobin Cuvettes are substantially equivalent to the claims and published specifications of the HemoCue Hb 301 and HemoCue Hb Microcuvettes for blood donor screening (see Table 5-1 on the following page). Both products are currently marketed outside the US and conform to Directive 98/79/EC on In-vitro Diagnostic Devices.
The two systems are similar in design, operating principles and technological characteristics. They have comparable precision and are similarly affected by pre-analytical factors such as fingerstick sampling. Both methods generally show less variability with venous samples than with fingerstick capillary samples.
Laboratory and clinical studies utilizing the hemiglobincyanide (HiCN) reference method according to ICSH, and hematology analyzers traceable to this reference, have demonstrated that the DiaSpect Hemoglobin T and DiaSpect Cuvettes are comparable to a variety of hematology analyzers marketed in the US.
