A wikipedia of Dr. D'Adamo's research

Strength Scale	Grade	Value	Appearance of reaction
4+	Complete	12	A single agglutinate. No free cells detected.
3 1/2+	4+w or 3+s	11
3+	3+	10	Strong reaction. A number of large agglutinates.
2-1/2+	3+w or 2+s	9
2+	2+	8	Large agglutinates in a sea of smaller clumps, no free cells.
2+w	2+w	7
1-1/2	1+s	6	Many medium and small agglutinates and a background of free cells
1+	1+	5	Many small agglutinates and a background of free cells
1+w	1+w	4	Many very small agglutinates; with many free cells
�+ or -	+/ macro	3	Weak granularity in cell suspension. A few macroscopic agglutinatesbut numerous agglutinates microscopically
Trace or micro	(+) macro	2	Appears negative macroscopically. A few agglutinates of 6-8 cells inmost fields
Questionable or micro	0	1	Rare agglutinates observed microscopically
0	0	0	An even cell suspension. No agglutinates observed microscopically.
