Omaha, NE – Streck offers two new configurations of LBC?Chex™, the first and only lamellar body count
control on the market. Lamellar bodies have been analyzed as an indirect estimate of fetal lung maturity
and potential indicator of respiratory distress syndrome.

LBC?Chex is convenient and easy to use. Laboratory scientists use the control in the same manner as a
patient sample of amniotic fluid – no dilution required, which saves time and reduces the potential for
testing error

The new configurations are:

3 x 3.0ml Level 1, catalog number 200099

3 x 3.0ml Level 2, catalog number 200100

Also available is the original configuration: 3 x 3.0ml, Level 1,2,3 – catalog number 200098.

LBC?Chex verifies the hematology instrument is accurate for the lower linearity limit of the platelet (PLT)
parameter. Available in three clinically significant levels, LBC?Chex tests lower parameters than standard
CBC controls and calibration materials. It is assayed for the Sysmex® XE?2100™, XE?5000™, XN?10™ and
XN?20™, and Beckman Coulter® LH 700 series and UniCel® DxH™ 800.

LBC?Chex features 30?day open?vial stability and 105?day closed?vial stability. It is packaged in plastic
3.0ml cap?pierceable vials.  

For Research Use Only. Not for use in diagnostic procedures.

Streck also offers Cell?Chex®, a body fluid procedural control for red blood cell and white blood cell
counts, crystal identification and white blood cell differentiation; and Cell?Chex® Auto, a three?level
spinal and body fluid control for evaluating the accuracy and precision of hematology instruments that
measure blood cell counts in patient body fluid samples.
