When the type is to be changed from serum (preceding sample) to urine (current sample), “serum” is set to a preceding type and “urine” is set to a measurement type at number 1 in a condition number. At condition number 1, the wash type is pattern 1, with washing performed once with detergent 1. Where the preceding sample is serum and the current sample is CSF, the condition number is 2 and the wash type is pattern 2, with washing performed twice using detergent 1 and once with detergent 2. Where the preceding sample is urine and the current sample is CSF, the condition number is 3 and the wash type is pattern 3, with washing performed once with detergent 1, once with detergent 2, and once with water. In the case of pattern 4, washing is performed three times with detergent 1.

The present technology is directed to extraction devices, systems, and methods for controllably withdrawing and transferring fluid samples, such as blood, from a sample collection container to a testing device. For example, some embodiments of the present technology provide fluid extraction devices that include a fluid control module, a housing containing a receiving element and a suction element, and an actuator. To transfer blood from a sample collection container to a testing device, a user places the sample collection container over the receiving element and inserts the testing device into an outlet of the fluid control module. The user then pushes a lever or otherwise actuates the actuator, which automatically withdraws a predetermined volume of blood from the sample collection container and transfers it to the testing device positioned at the outlet of the fluid control module.
