Dissection of discrepant LAMP assay results according to the ‘scrub typhus infection criteria’ (STIC).

The LAMP results of each individual sub-group of STIC were grouped into positive/negative to allow for comparisons to other diagnostic modalities. Serological median reciprocal admission (Adm) and follow-up (Fup) IgM titers are shown as well as supportive diagnostic evidence from PCR, isolation and rapidtests (percentage of positive results). Discrepancies had no association with ‘days of fever / illness’ prior to admission.
