  A systematic analysis of nucleon-nucleon scattering amplitudes is available
up to a laboratory energy of $3$~GeV in case of the $pp$ system and up to $1.2$
GeV for $pn$. At higher energies there is only incomplete experimental
information on $pp$ elastic scattering, whereas data for the $pn$ system are
very scarce. We apply the spin-dependent Glauber theory to calculate spin
observables of $pd$ elastic scattering at $3$-$50$ GeV/c using $pp$ amplitudes
available in the literature and parametrized within the Regge formalism. The
calculated vector $A_y^p$, $A_y^d$ and tensor $A_{xx}$, $A_{yy}$ analyzing
powers and the spin-correlation coefficients $C_{y,y}$, $C_{x,x}$, $C_{yy,y}$,
$C_{xx,y}$ can be measured at SPD NICA and, thus, will provide a test of the
used $pN$ amplitudes.
