Note: Comparison of IsoCode STIX and FTA Gene Guard Collection Matrices as Whole-Blood Storage and Processing Devices for Diagnosis of Malaria by PCR

摘要

We compared two collection devices, IsoCode and FTA, with whole blood for the diagnosis of malaria by PCR (n = 100). Using whole blood as the reference standard, both devices were sensitive for the detection of single-species malaria infections by PCR (≥96%). However, the detection of mixed infections was suboptimal (IsoCode was 42% sensitive, and FTA was 63% sensitive).
