According to step 2 secrets in scurvy:
PTT is normal as well as PT, BT and platelet count.

Everything is normal because in scurvy, vitamin C deficiency leads to impaired collagen synthesis, causing capillary fragility, poor wound healing, hence bleeding but there's no intrinsic, extrinsic pathway, or platelet dysfunction.
