AggRAM - 4-channel platelet aggregation analyzer

AggRAM - 4-channel platelet aggregation analyzer

The four-channel optical aggregometerAggRAM, is intended for carrying out research on platelet aggregation (collagen, epinephrine, ADP, arachidonic acid) and determining the von Willebrand factor.

Processing of results - is carried out automatically, using software installed on a personal computer. The software calculates the slope (first and second wave of aggregation), the maximum percentage of aggregation, the time of maximum aggregation, lag-phase, calculation of the area under the curve (AUC), the ability to manually edit the options and smooth the curve.

Search and store results - the original software allows you to search, save and automatically duplicate the results of patient analyzes, controls and calibrators. Two-way communication with LIS.

Quality control - the ability to build Levey-Jennings chart and conduct an inspection according to the Westgard rule.


  • Measurement of aggregation by light transmission (Bourne method)
  • 4 microvolume measuring channels (250 μl) and standard volume (500 μl)
  • Tests: Platelet aggregation and Ristocetin cofactor (von Willebrand factor determination)
  • Two-way LIS interface (LIS)
  • Unsurpassed capabilities in choosing software solutions
  • Refillable magnetic stirrers
  • Disposable siliconized glass tubes
  • Programming agitator speed
  • Enhanced patient results, quality control and standards databases. Data retrieval and function full data backup for security purposes
  • Preservation of reference aggregation curves in databases and their imposition
  • A wide range of high quality aggregation reagents and ristocetin cofactor.
  • Bar code reader (optional)


  • Pre-installed programs with standard platelet activators: collagen, epinephrine, arachidonic
  • acid, ADP, ristocetin
  • Possibility of additional programming of tests with activators used by the user /
  • screenings: RIAT, HIT, inhibition, research goals, etc.
  • Only 25 or 50 μl reagent / 225 or 450 μl platelet-rich plasma (PRP)
  • Real-time results


  • Building Levey-Jennings graphics.
  • Calculation of the angle of inclination of the first and second wave of aggregation, the maximum percentage of aggregation, time of maximum aggregation, lag phase, surface area under the curve.
  • Smoothing the curve on the reaction graph.
  • Overlay one aggregatogram to another. This procedure will allow you to make a visual comparison of two patients (for example, healthy and sick). The capabilities of the device allow you to impose on one chart several aggregatograms.
