Objectives

The primary objective of this tender is to procure and supply specific diagnostic kits—namely Diethylene Triamine Pent Acetate Acid Kit, Macro Aggregate Albumil Kit, Tin Colloid Kit, and Mibi Kit—for a period of 12 months to Livingstone Tertiary Hospital. The aim is to ensure the hospital has a reliable supply of these medical kits to facilitate diagnostic procedures related to renal imaging, pulmonary scintigraphy, reticuloendothelial system diagnostics, and myocardial perfusion scintigraphy, among others.

Scope

The scope of the tender encompasses the supply and delivery of the following kits:

• Diethylene Triamine Pent Acetate Acid Kit
• Macro Aggregate Albumil Kit
• Tin Colloid Kit
• Mibi Kit

The delivery is to be made over a 12-month period directly to Livingstone Tertiary Hospital, including the provincial site in Port Elizabeth. The successful bidders may be awarded to one or multiple suppliers, with the stipulation that the difference in point scores between the highest and lowest scoring bidders does not exceed 10%.
