DiagnoVac Gel & Clot Activator Tube
During the centrifugation of the DiagnoVac Gel & Clot Activator Tube , an inert gel separates the serum and the blood clot preventing the contamination of the serum from the separated cellular components. For example, the serum for certain analytes such as potassium, phosphorus and glucose must be separated from the cells within a few hours – otherwise the results will be significantly distorted. Using DiagnoVac Gel & Clot Activator Tube routine analytes in clinical chemistry such as potassium and glucose are still stable after a week of storage at 2-8ºC. Clinical evaluations of special chemistry demonstrate a high degree of analyte stability with the acrylic gel in the DiagnoVac Gel & Clot Activator Tube, with detection of >90% of the therapeutic drugs and other special analytes (proteins/ peptides, steroids and vitamins) tested. As a result of the type of gel used in the DiagnoVac Gel & Clot Activator Tubes, short centrifugation times of 5 minutes at 3000 g can be achieved. The stability of the gel barrier is a distinct advantage during transport and storage. The main advantages of gel tubes versus non-gel tubes are:
• Stable barrier between serum and clotted blood, therefore better analyte stability
• Better sample quality
• Optimisation of the work flow: Short centrifugation time, sample processing and archiving in the primary tube
• No possibility of misidentification due to the use of secondary tubes
Clotting times
The minimum recommended coagulation time for DiagnoVac Gel & Clot Activator Tube for patients who have not received anticoagulation treatment is 30 minutes.
Centrifugation conditions
1300-2000 g for 10 minutes or alternatively, 3000 g for 5 minutes at 18-25°C1 .
Mixing recommendation
Serum Separation Tubes should be gently inverted 180° and back 5-6 times.
Effects of temperature
DiagnoVac Gel & Clot Activator Tube should be stored at 4-25°C and protected from direct sunlight during storage. Cooling of the tube by or during centrifuging can affect the movement capability of the gel. The optimum separation of serum and coagulated blood is achieved at a temperature of 20-25°C.
Clot activator
DiagnoVac Gel & Clot Activator Tubes contain silica particles
