Test ID: LMALP    
Malaria PCR with Parasitemia Reflex, Varies

Method Description Describes how the test is performed and provides a method-specific reference

DNA from EDTA-anticoagulated whole blood is extracted and tested using real-time polymerase chain reaction (PCR) on the LightCycler 2.0 instrument (Roche Applied Science) with primers and fluorescence resonance energy transfer (FRET) probes. A genus-specific primer set corresponding to 18S rRNA is used to amplify target sequence. One pair of FRET hybridization probes was designed for Plasmodium falciparum over a region containing base pair mismatches allowing for differentiation of other Plasmodium species by use of melting curve analysis, while a second probe set is specific for P knowlesi.(Babady NE, Sloan LM, Rosenblatt JE, Pritt BS: Detection of Plasmodium knowlesi by real-time polymerase chain reaction. Am J Trop Med Hyg. 2009 Sept;81(3):516-518)


Slides are used to determine percentage of parasitemia if PCR is positive.

Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Monday through Sunday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

Same day/1 to 3 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

7 days

Performing Laboratory Location Indicates the location of the laboratory that performs the test
