Sensitivity and Specificity of Nucleic Acid Sequence-Based Amplification Method for Diagnosis of Cutaneous Leishmaniasis
Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...
متن کاملAppropriate time for test-of-cure when diagnosing gonorrhoea with a nucleic acid amplification test.
Culture is commonly regarded as the gold standard for diagnosis of Neisseria gonorrhoeae. However, nucleic acid amplification tests (NAATs) have rapidly replaced culture for diagnostics in many settings. The aim of the present study was to investigate the appropriate time for test-of-cure (TOC) when NAATs are used for diagnosis of gonorrhoea. In total, 30 patients (28 men and 2 women) provided ...
متن کاملInhibition and facilitation of nucleic acid amplification.
Factors that inhibit the amplification of nucleic acids by PCR are present with target DNAs from many sources. The inhibitors generally act at one or more of three essential points in the reaction in the following ways: they interfere with the cell lysis necessary for extraction of DNA, they interfere by nucleic acid degradation or capture, and they inhibit polymerase activity for amplification...
متن کاملPolymerase chain reaction amplification of Guthrie card deoxyribonucleic acid: extraction of nucleic acid from filter matrices.
This study evaluated two deoxyribonucleic acid (DNA) extraction methods for Guthrie card bloodspots. Our water-based extraction technique was compared with a commercial kit (GFX extraction system). In contrast to our nondenaturing method, the GFX system utilizes chaotropes to extract DNA. Extracted DNA is subsequently purified by selective elution from a glass fiber matrix. To evaluate DNA extr...
متن کاملDiagnostic Devices for Isothermal Nucleic Acid Amplification
Since the development of the polymerase chain reaction (PCR) technique, genomic information has been retrievable from lesser amounts of DNA than previously possible. PCR-based amplifications require high-precision instruments to perform temperature cycling reactions; further, they are cumbersome for routine clinical use. However, the use of isothermal approaches can eliminate many complications...
