The Sinapi Sputum Cup was designed to reduce the amount of mucous specimens that are rejected at labs causing a delay in diagnosis and treatment of patients with tuberculosis (TB) and increasing the spread of TB: Clear MIN/MAX indicators ensure that a sufficient amount of specimen is obtained. Lid opening requires minimal twisting of the wrists reducing the risk of injury due to a high lab specimen load. The lid screws on securely minimising leakage during transport. Small increment measurements allow laboratory staff to accurately add buffer to the specimen.
