Sample size
High quality results with precious hard to draw samples.
The challenge
Blood collection and laboratory testing in pediatric populations present multiple challenges (i.e., 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.
The solution
Our VITROS® MicroSlide technology are ideal for this challenge as it requires only 2.7 µL to 11 µL of sample.
Furthermore, to alleviate these issues is 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 to further 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).
