Uterine Culture Instruments 1.
Shown are, the Kalayjian culture instrument at the top, the unguarded swab in the middle, and the metal Knudsen instrument. Both the Kalayjian and the Knudsen are designed to protect the swab as it is passed through the vagina and cervix hence providing the opportunity to secure a true culture of the uterine lumen.
