Diagnostica Stago Start 4 Coagulation Analyzer Manual |top|

The Diagnostica Stago Start 4 relies on a precise combination of mechanical reliability and rigorous pre-analytical technique. To guarantee peak performance:

Dispense the reagent rapidly into the measurement cuvette. The electronic trigger on the pipette will automatically start the channel's timer.

Allow the sample to incubate for the time specified in the reagent manufacturer’s instructions (e.g., 3–5 minutes for APTT). Step B: Measurement Transfer the cuvette to one of the 4 measuring channels. The magnetic field will begin to vibrate the ball.

Use the connected electronic pipette to draw the appropriate volume of the activated reagent. diagnostica stago start 4 coagulation analyzer manual

The analyzer has an incubation block that must be at 37°C ± 0.5°C. Allow sufficient time for the instrument to reach this temperature before running samples. The Diagnostica Stago Start 4 relies on a

Limitations and considerations The START 4’s smaller size inherently limits sample throughput and parallel assay capacity; laboratories with high volumes may require larger platforms. Certain specialized coagulation tests or advanced hemostasis assays might not be available or validated on the platform, necessitating referral to reference labs. Additionally, reagent lot variability and maintenance lapses can affect result consistency, underscoring the importance of QC and regular calibration.
