NTE|15||* CRITICAL VALUE
NTE|16||This assay has a sensitivity of at least 95% and a
NTE|17||specificity of 75% at the 1.0 U/mL cut-off.  For results
NTE|18||>4.0 U/mL the specificity is 95%. HIT remains a clinical
NTE|19||diagnosis and results should be interpreted using the 4T's
NTE|20||probability score.
