Impact factor (IF) of a journal is the measure reflecting the average number of citations to recent articles published in the journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones. Impact factors of the journals are calculated yearly. The impact factor relates to a specific time period; it is possible to calculate it for any desired period. In any given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years. Biomarker impact factor is also been calculated on same basis of the total number of citations and journal's self-citations received by a journal's published documents during the previous years. Biomarker impact factor calculation shows it efficiency in the field of journals and will help to raise the impact factor in the near future. The impact factor is used to compare different journals within a certain field. Biomarker impact factor is highly dependent on the academic discipline, possibly on the speed with which articles related to the biomarker journal covering all aspects of biomarker research and clinical applications.
