HCV infection can be detected by anti-HCV screening tests (enzyme immunoassay) 4–10 weeks after infection. Anti-HCV can be detected in >97% of persons by 6 months after exposure.
How soon after exposure to HCV can HCV RNA be detected by PCR?
HCV RNA appears in blood and can be detected as early as 2–3 weeks after infection.

IMO at 18 wks you are good to go but the CDC says 6 months to be conclusive.
Yes and my hiv tests surpassed 24 weeks but my only hcv test was during the 18th/19th week after my exposure
You do not need further HCV testing, testing for HCV is conclusive for HCV antibodies at 24 weeks
Would you recommend further hcv testing?
Your test was conclusive. HCV will not affect your HIV test results. You do not need further testing.
