Abstract: A radionuclide quality control test kit includes a disposable chromatography chamber. A premeasured amount of a solvent solution is provided in the chamber. A disposable test strip has spaced opposite first and second ends. The first end is immersible in the solvent solution in the chamber upon being spotted by a radiopharmaceutical to be tested to enable the solvent solution to ascend the strip to the second end whereat radiochemical impurities of the radiopharmaceutical migrating to the second end are radiologically countable to permit computation of such impurities.

Abstract: A multipurpose double barrel syringe is manufactured by disassembling a first syringe having a first predetermined capacity, a first cylinder, a first hypodermic needle of a first gauge at a first end thereof, a first piston plunger having a plunger tip with a smooth seating surface and a rear indentation and a first collar extending radially therefrom at a spaced opposite second end thereof, and a second syringe having a second cylinder with a second predetermined capacity less than the first predetermined capacity, the second cylinder having a second collar extending substantially radially therefrom at a first end thereof, a second needle of a second gauge with a tip and a base and a second piston plunger having a piston rod having a second plunger tip coaxially mounted at a first end thereof coaxially slidably mounted in the second cylinder for movement in axial directions and a third collar extending radially therefrom at a spaced opposite second end thereof.

Abstract: Citrated platelet-rich blood plasma is added to Tc.sup.99m macroaggregated albumin or Tc.sup.99m human serum albumin microspheres and counted in a well scintillation counter to provide the preclot count. Calcium chloride is added to the combination to initiate the clotting process. An anticoagulant is added to the solution after the formation of a clot to terminate the clot reaction. The residual clot is washed in a normal saline solution. The washed clot is resuspended in a saline solution and is recounted in the well scintillation counter to provide the post-clot count and the clotting time.
