RESEARCH METHODOLOGY 2.2 MARKET SIZE ESTIMATION • Both, top-down and bottom-up approaches were used to anticipate and validate the size of the U.S. IVD market and estimate the size of various other dependent submarkets. • Major players in the market were identified through secondary research, and their market revenues were determined through primary and secondary research. Secondary research included the study of the annual and financial reports of the top market players, whereas primary research included extensive interviews of key opinion leaders such as CEOs, directors, and marketing executives. The percentage splits, shares, and breakdowns of the products market were determined using secondary sources and verified through primary sources. • All possible factors that affect the markets included in this research study have been accounted for, viewed in extensive detail, verified through primary research, and analyzed to get the final quantitative and qualitative data. The market size for top-level markets and subsegments is normalized, and the effect of inflation, economic downturn, and regulatory and policy changes or other factors are not accounted for in the market forecast. This data is combined and added with detailed inputs and analysis from MarketsandMarkets and presented in this report. • The following figure shows an illustrative representation of the overall market size estimation process used for this study. • FIGURE 3 BOTTOM-UP APPROACH • • • [email protected] www.marketsandmarkets.com 8
