Table 4 Bland-Altman analysis comparing data obtained by flow cytometry and Chipcytometry

From: Immunophenotyping of cerebrospinal fluid cells by Chipcytometry

Sample/cell population Bias 95% limits of agreement
All cells and samples − 1.054 − 17.31 15.20
Cell counts ≥ 5/μl 0.008750 − 7.961 7.978
Cell counts < 5/μl − 1.585 − 20.87 17.70
T cells 1.315 − 23.62 26.25
B cells − 0.3833 − 4.463 3.696
Monocytes − 5.420 − 26.62 15.78
T cell CD4:CD8 ratio 0.2733 − 1.638 2.185
  1. A bias close to zero indicates that both methods generate nearly identical results
