VH04
4-Part
Analyzer
Real eosinophil differentiation for 19 species. The first analyzer that makes EOS# and EOS% fully reportable — with a dedicated histogram.
Real 4-part impedance
with VH04 Lyse
A dual-lyse process enables precise eosinophil separation — a parameter critical for parasitic and allergic conditions common in veterinary patients.
Sample collection
10 μl whole blood or 20 μl pre-diluted — minimal invasion for small animals.
First lyse pass
VH04 Lyse differentiates lymphocytes and monocytes with precision.
Second lyse pass
Remaining WBCs are shrunk to isolate neutrophils from eosinophils.
4-part result
EOS#, EOS%, and a dedicated eosinophil histogram are fully reportable.
26 reported parameters
Including EOS# and EOS% as fully reportable values — highlighted below — alongside a dedicated eosinophil histogram.
★ Teal-highlighted parameters include the unique eosinophil differential — critical for parasite and allergy screening.
19 species + customizable
From household companions to exotic wildlife — every species has validated reference ranges built in, with custom species configuration supported.
