NTE|1||* CRITICAL VALUE
NTE|2||This assay has a sensitivity of at least 95% and a
NTE|3||specificity of 75% at the 1.0 U/mL cut-off.  For results
NTE|4||>4.0 U/mL the specificity is 95%. HIT remains a clinical
NTE|5||diagnosis and results should be interpreted using the 4T's
NTE|6||probability score.
