WESTERN BLOT	PEPTIDE ASSAY HTLV-I     HTLV-II	FINAL INTERPRETATION
Positive Positive Positive Positive	R      NR NR      R NR      NR Inconclusive  Inconclusive	HTLV-I Positive HTLV-I Positive HTLV Positive - Inconclusive Viral Type(a) HTLV Positive - Inconclusive Viral Type (a)
Indeterminate Indeterminate Indeterminate Indeterminate	R      NR NR      R NR      NR Inconclusive  Inconclusive	HTLV-I Positive (b) HTLV-II Positive (b) Inconclusive Inconclusive
Negative	No additional testing necessary	Negative

Notes:

(a) These samples are positive for HTLV but cannot be classified by the peptide assay alone. Additional polymerase chain reaction (PCR) testing may be recommended.
(b) These samples may be considered positive for HTLV-I or HTLV-II, provided the Western blot pattern displays reactivity with p24.
