SX | Marker studies not available or not performed. |
S0 | Marker study levels within normal limits. |
S1 | LDH <1.5 × Nb and hCG (mIu/ml) <5,000 and AFP (ng/ml) <1,000. |
S2 | LDH 1.5–10 × N or hCG (mIu/ml) 5,000–50,000 or AFP (ng/ml) 1,000–10,000. |
S3 | LDH >10 × N or hCG (mIu/ml) >50,000 or AFP (ng/ml) >10,000. |
AFP = alpha-fetoprotein; hCG = human chorionic gonadotropin; LDH = lactase dehydrogenase; N indicates the upper limit of normal for the LDH assay.
