where:
• A low serum AFP was <= 100 ng/mL.
• The method for analysis and the reference range for AFP were not given but from Table 1 the reference range is inferred as being <= 10 ng/mL.
• A low serum HCG was <= 5,000 IU/L.
• The method for analysis and the reference range for HCG were not given but from Table 1 the reference range is inferred as being <= 10 IU/L.
total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 3
• The higher the score the worse the overall prognosis.
