Table 2.

Haptoglobin (Hp) Concentration and Phenotype in PTS Cases and Controls (No PTS)

	PTS Subjects n=50	No PTS n=58	Expected Ratio for Seattle Area^b [36]

Hp (mg/dl)^a	200 ± 90	192 ± 71	---

Hp Phenotype
Hp 1-1	11 (22 %)	7 (12 %)	14%
Hp 2-1	22 (44%)	28 (48%)	48%
Hp 2-2	17 (34%)	23 (40%)	38%

normal range for Haptoglobin (100-300 mg/dl), p = 0.57

There is not a statistically significant difference in Hp phenotype distribution in patients who developed PTS compared to those who did not. (χ² = 0.250, DF=2, p=0.883)
