We implement a one-loop analysis of the ρ parameter in the Left Right Twin Higgs model, including the logarithmically enhanced contributions from both heavy fermion and scalar loops. Numerical analysis indicates that the one-loop corrections are dominant over the tree-level contributions in most regions of parameter space. The experimentally allowed values of the ρ-parameter divide the allowed parameter space into two regions; less than 670 \rm GeV and larger than 1100 \rm GeV roughly, for the symmetry breaking scale f. Therefore our result significantly reduces the parameter space which are favorably accessible to the LHC.
