Test ID: ACARP    
Acanthamoeba species Molecular Detection, PCR, Ocular

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

The assay is performed on the Roche LightCycler (LC) 480 II instrument, following DNA extraction on the Roche MagNA Pure or the Siemens Tissue Preparation System (TPS). The LC 480 II instrument is an automated instrument that amplifies and monitors the development of target nucleic acid (amplicon) after each cycle of PCR.

 

The DNA target for this PCR assay is a gene encoding the nuclear small subunit ribosomal 18S rRNA.

 

The PCR mix contains a forward and reverse primer specific for Acanthamoeba species template amplification and 1 TaqMan probe (CY5). The CY5 probe contains a fluorophore (5'-end) and a quencher (3'-end) in close proximity; the quencher inhibits the fluorescence signal from the fluorophore while the probe is intact. After the probe anneals to the targeted Acanthamoeba 18S rRNA, it is subsequently degraded by a DNA polymerase with 5'-3' exonuclease activity, resulting in release of the fluorophore and production of detectable fluorescent signal.(Qvarnstrom Y, Visvesvara GS, Sriram R, da Silva AJ: Multiplex real-time PCR assay for simultaneous detection of Acanthamoeba spp, Balamuthia mandrillaris, and Naegleria fowleri.

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 Saturday

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.

2 days

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
