A test pen includes an integral hollow pen barrel. The hollow pen barrel is divided into four sections in order being a dip section, a testing and observation section, a drying section, and a sealed rear section. The dip section has a front opening allowing a slender water-absorbing member to pass therethrough. An air balance hole is provided on the dip section of the pen barrel to facilitate liquid siphoning. A pen cap for capping the dip section has a flexible inner fringe for keeping the dip section airtight. A rear plug is provided for sealing the rear section. A testing member is installed in the testing and observation section. The testing member includes a support card, a solid carrier, a conjugate release pad partially overlapping the front end of the solid carrier, an absorbing pad partially overlapping the rear end of the solid carrier, and a cover tape.
