Abstract

Loop-mediated isothermal amplification (LAMP) of DNA offers the ability to detect very small quantities of pathogen DNA following minimal tissue sample processing and is thus an attractive methodology for point-of-care diagnostics. Previous attempts to diagnose malaria by the use of blood samples and LAMP have targeted the parasite small-subunit rRNA gene, with a resultant sensitivity for Plasmodium falciparum of around 100 parasites per μl. Here we describe the use of mitochondrial targets for LAMP-based detection of any Plasmodium genus parasite and of P. falciparum specifically. These new targets allow routine amplification from samples containing as few as five parasites per μl of blood. Amplification is complete within 30 to 40 min and is assessed by real-time turbidimetry, thereby offering rapid diagnosis with greater sensitivity than is achieved by the most skilled microscopist or antigen detection using lateral flow immunoassays.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several studies reported high sensitivity and specificity of LAMP compared with microscopy or PCR in nonpregnant populations.

    “Several studies that compared the LAMP method to microscopy, PCR and RDT, reported high sensitivity and specificity compared with microscopy or PCR in nonpregnant populations [34–37].”

  • LAMP is a newer alternative to PCR and qPCR that does not require DNA purification, uses simple instrumentation, and can be completed in less than 1 hour.

    “Loop-mediated isothermal amplification (LAMP) is a newer alternative to PCR and qPCR. This method does not require DNA purification, utilizes simple instrumentation (water bath or a heat block), and can be completed in less than 1 h [33,34].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
