Overcoming challenges caused by low or insufficient testing volumes of serum or plasma.
Blood collection and laboratory testing in pediatric populations present multiple challenges (e.g., draw volume limitations, vein collapse and high hematocrit).
These result in low or insufficient serum or plasma volume available for testing and potentially no reportable laboratory results.
Our VITROS® MicroSlide technology is ideal for this challenge as it requires only 2.7 µL to 11 µL of sample.
Furthermore, we continue to reduce the sample volume required for laboratory testing. Now you can achieve this with VITROS® XT MicroSlides. Featuring dual-test capability, these innovative slides are designed further to reduce sample size while maintaining analytical performance versus a conventional single assay test element.
The total sample volume to run the 12 XT MicroSlides is 45.6 μL, ranging from 2.7 μL for GLU to 5.0 μL for ALKP, and decreasing the sample volume by 49% from the low 89.5 μL sample volume required for the current VITROS MicroSlide products.

The SMART metering feature automatically checks for bubbles and clots/debris every time the system aspirates or dispenses fluid. This acts as an analytical control process for each test, ensuring result integrity is maintained.
If the sample is insufficient, or if there are bubbles or a clot, the analyzer will return the precious sample to the tube ('Save the Sample' feature).
