Thrombotrack™ Solo – Instruction Manual 5. Plug the AC adaptor into the mains socket outlet. 6. Turn on the Thrombotrack™ Solo with switch (1). IMPORTANT! The mains voltage must coincide with the technical specifications of the instrument. The mains circuit must have adequate fuse protection. The instrument must be connected to a properly grounded outlet only. If in doubt about mains voltage or the circuit in general, contact a qualified electrician. Do not connect other electrical appliances that may cause interference to the circuit. Do not set up the instrument near electrical appliances causing electric interference (appliances bearing no CE-label). Avoid connection to circuits to which other appliances having a high current draw (e.g. centrifuges) or which turn on and off frequently (e.g. refrigerator, water bath, etc.) are connected. Ensure that the power cord cannot be stepped on. All connections to the instrument should be made with the instrument turned OFF. 2.5

Turn off Thrombotrack™ Solo

1. Turn the Thrombotrack™ Solo off using the “POWER” switch (1). 2. Remove all used cuvettes and cover the instrument with the dust cover supplied.

Thrombotrack™ Solo – Instruction Manual 3.4

The measuring system A magnet (1) is located beneath the cuvette (5), which causes the steel ball (2) to rotate. This enables the sample to be optimally and gently homogenised (4). A sensor (3) is used to monitor the rotation of the steel ball. As a result of clot formation, the viscosity changes and causes the ball either to stop or divert towards the middle of the cuvette. In both cases, the sensor signals the change and stops the measurement. The clot formation is reliably detected and without interference from turbid plasma.

Figure 3 When coagulation starts, the viscosity of the sample changes and affects the continuous motion of the ball. When a strong clot is formed, the steel ball will stop as shown in figure 4. When the clotting starts the viscosity of the sample changes, affecting the continuous motion of the ball. Clotting in the normal range will stop the ball (Fig. 2).

Figure 4 A weak clot will deflect the ball towards the center of the cuvette's base (figure 5). The sensor detects the changed course of the ball and stops the measurement.

Figure 5 In both cases the start of the clotting process is positively detected, irrespective of the sample's cloudiness.

Thrombotrack™ Solo – Instruction Manual

4 Preparation prior to operation The operating conditions and how to turn Thrombotrack™ Solo on are described in chapter 2.3 and 2.4. 4.1

Connecting start pipette

A start pipette for automatic start of measurement can be connected to the back of the instrument. 4.2

Loading the steel ball dispenser

Unscrew the steel ball dispenser tip.

Fill steel balls from the steel ball tube into the ball dispenser.

Screw the steel ball dispenser tip on again.

5 Operating procedure 5.1 General The operating procedures described in this chapter include the specific procedures for Thrombotest™, Normotest™, Nycotest® PT, Nycoplastin™ and Cephotest™. It is presupposed that reagent preparation is completed and correct. For PT tests the normal time and ISI are programmed as described in chapter 3.3.2. When working with the Thrombotrack™ Solo, always pay attention to methods and reagents described in the package inserts. Discrepancies can cause errors in measurements. Chapter 6, “User guidelines”, gives information related to the use of reagents, calibrators and controls. 5.2 Starting up Turn the instrument on by using the switch on the back of the instrument. Message “cold” appears. The “cold” message remains until the Thrombotrack™ Solo has reached the correct operating temperature. When working temperature is reached “0.0” appears. Instrument is now ready for use. Note: At a room temperature of approx. 23°C the heating-up time is approx. 10 - 15 minutes.

Thrombotrack™ Solo – Instruction Manual 5.3 General information during operation Before starting the specific operating procedure, the following information should be considered: Cuvettes:

Single cuvettes are used

Dispensing steel balls:

When dispensing steel balls, by means of the steel ball dispenser, into each cuvette, the dispenser should be placed on the cuvette in such a manner that the steel ball is kept from ricocheting.

Pre-heating

In the operating procedures for Thrombotest™, Normotest™ and Nycotest® PT it is expected that the method specific reagent volume is heated up 37°C. For Nycoplastin™ and Cephotest™, a sufficient volume for running the required number of tests must be pre-heated. In order to reach the temperature of 37°C in the heating position, the volume of the reagent must not exceed 1.2 mL. The time required depends on the reagent temperature and may take 5 - 8 minutes.

Incubation timer

For activation of incubation timer, see chapter 3.3.3

6 User guidelines 6.1

Use of reagent

The package inserts for reagents from Axis-Shield PoC provide all information necessary for reagent preparation and use. The same applies to the respective controls and calibrators. Always follow this information; improper use may result in incorrect results. Where several options of performance are described (e.g. for automated instruments), the instructions concerning manual performance of the test prevail. When using smaller volumes than those stated in the package inserts, it is important to reduce all pipetting volumes by same percentage. Make sure that the total sample volume is not less than 150 µl.

Thrombotrack™ Solo – Instruction Manual 6.2 Calibration and interpretation of results The measured time is the time from adding the sample (or start reagent) until the occurrence of coagulation. This time value is the basis for an evaluation. PT kits from Axis-Shield PoC contain inserts with reagent and batch specific calibration data (Correlation tables). If there is any uncertainty regarding use of calibration data on the Thrombotrack™ Solo, contact your local distributor. The package insert from Axis-Shield PoC provides information on how to interpret results obtained. The description of how to enter normal time and ISI on the Thrombotrack™ Solo is given in chapter 3.3.2. 6.3 Quality Control To control the instrument, reagent and test method, special control plasmas are used. In the package inserts from Axis-Shield PoC, the recommended controls are listed. The package inserts for the controls give all information for preparation and use of the control plasmas. Always follow this information; improper use may result in incorrect results. The control kits also included data-key with recommended values. Control plasmas available from Axis-Shield PoC are: Control plasmas Control Plasma Normal Control Plasma AK Control Plasma Abnormal Control Plasma Heparin

Thrombotest Normotest

Nycotest PT

Nycoplastin

Cephotest

R R

R means recommended values stated in the data-keys. 6.4

Operational check of the Thrombotrack™ Solo

Start an analysis without placing a cuvette in the measuring channel. After 3.8 seconds “E5” will appear in the display, meaning the instrument has not detected a cuvette in the measuring channel.

Dispense a ball into a cuvette and fill it with at least 150µL distilled water or buffer. Place a cuvette in the measuring channel and press <START>. After a time longer than 3.8
