Strength ScaleGradeValue Appearance of reaction
4+Complete 12A single agglutinate. No free cells detected.
3 1/2+4+w or 3+s11
3+3+10Strong reaction. A number of large agglutinates.
2-1/2+3+w or 2+s9
2+2+8Large agglutinates in a sea of smaller clumps, no free cells.
2+w2+w7
1-1/21+s6Many medium and small agglutinates and a background of free cells
1+1+5Many small agglutinates and a background of free cells
1+w1+w4Many very small agglutinates; with many free cells
�+ or -+/ macro3Weak granularity in cell suspension. A few macroscopic agglutinatesbut numerous agglutinates microscopically
Trace or micro(+) macro2Appears negative macroscopically. A few agglutinates of 6-8 cells inmost fields
Questionable or micro01Rare agglutinates observed microscopically
000An even cell suspension. No agglutinates observed microscopically.
