Figure 1From: Blood profile holds clues to role of infection in a premonitory state for idiopathic parkinsonism and of gastrointestinal infection in established diseaseBland-Altman contrast of difference in and average of lymphocyte counts (×109/l) by two methods in 163 subjects. Difference expressed as subset sum (CD3+, CD19+ and CD16+56+)* minus FBC value**. Regression line and 95% upper & lower limits of agreement shown. Difference between subset sum and routine lymphocyte count is small around grand mean for average count, its variability constant over the range.*Four-colour fluorescent cell labelling using the MultiTEST kit in TruCOUNT tubes and a FACSCalibur flow cytometer (Becton Dickinson, San Jose, California, USA).** Using XE2100, Sysmex UK Ltd., Wymbush.Back to article page
