Diagnostica Stago Start 4 Coagulation Analyzer Manual ((top))

Without the manual, users risk:

Ensure the instrument is on a stable, vibration-free surface.

Integrated thermal printer and alphanumeric keypad.

The Diagnostic Stago Start 4 Coagulation Analyzer is a compact, user-friendly device that measures various coagulation parameters, including prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, and more. This analyzer is designed for small to medium-sized laboratories, offering a reliable and efficient solution for coagulation testing.

16 sample wells (arranged in a 4x4 matrix) optimized at 37°C ± 0.5°C diagnostica stago start 4 coagulation analyzer manual

Unlike optical systems that measure changes in light transmission (turbidimetry), the Stago Start 4 utilizes a patented . This eliminates interference from lipemic, icteric, or hemolyzed samples.

Allow the instrument to sit powered on for at least 20 to 30 minutes until the incubation block reaches its stable operating temperature of 37°C ± 0.5°C . 4. Test Menu and Clinical Applications

This article serves as a general operational overview. Always consult the official printed Diagnostica Stago Start 4 instruction manual provided with your specific instrument serial number for definitive reference values, safety warnings, and compliance guidelines.

After incubation, move the cuvette to the measurement area and add reagent using the to automatically trigger measurement . Technical Specifications Specification Detection Channels 4 independent measurement channels Incubation Capacity 16 wells (4 cells x 4 columns) at 37°C Reagent Positions 2 positions at 37°C (one with a magnetic stirrer ) Display 4-line, 40-character backlit LCD Data Output Internal thermal printer and RS232 interface Maintenance & Troubleshooting Without the manual, users risk: Ensure the instrument

Missing magnetic ball; inactive reagent; extremely low fibrinogen level.

It is essential to run Quality Control samples (Normal and Abnormal levels) at the start of every shift.

Clean the exterior surfaces with a mild disinfectant.

Results marked with asterisks (*) often indicate that the reagent was not added quickly enough or the pipette was not used correctly, requiring a rerun . This analyzer is designed for small to medium-sized

Workflow and operation (typical steps)

Clean the internal optical sensors that track the magnetic ball position (this should ideally be handled by a certified biomedical technician). 6. Troubleshooting and Error Codes

Mechanical clot detection (Stago’s proprietary Viscosity-Based Detection System). Channels: 4 independent measuring channels.

Check the built-in thermal printer to ensure that the 40-column paper roll is threaded properly. 2. Reagent and Sample Incubation
