In addition, different anticoagulants can be utilized to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have diverse effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell forms (hemolysis) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. A number of miRNAs are identified to become expressed at high levels in specific blood cell forms, and these miRNAs are usually excluded from analysis to avoid confusion.Moreover, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies using these different beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are among one of the most often made use of high-throughput RT-PCR platforms for miRNA detection. Each uses a distinctive technique to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which final results in diverse detection biases. ?Data evaluation: Among the greatest challenges to date is definitely the normalization of circulating miRNA levels.

Spiking samples with RNA controls and/or normalization of miRNA levels to volume are some of the methods utilised to standardize analysis. Furthermore, various studies apply distinctive statistical strategies and criteria for normalization, background or handle reference s.
