Test Catalog

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

Monday through Sunday; Varies

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

Same day/1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

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
