Problems solved by technology

For example, overfilling of volume-sensitive blood culture bottles can lead to false positive result
On the other hand, insufficient patient sample volume in culture medium can lead to false negative results

Embodiment Construction

[0027] In some cases, a patient sample is tested for the presence of one or more potentially undesirable microorganisms, eg, bacteria, fungi, or yeasts (eg, Candida). Various techniques may be employed to assist in detecting the presence of microorganisms and other types of biological material, specific types of cells, biomarkers, proteins, antigens, enzymes, blood components, and / or the like during diagnostic testing. Examples include, but are not limited to, molecular polymerase chain reaction (PCR), magnetic resonance and other magnetic analysis platforms, automated microscopy, spatial clone separation, flow cytometry, analysis of whole blood ("culture-free") specimens (e.g., NGS) and related techniques, morphokinetic cytometry and / or other common or evolving advanced techniques used in clinical laboratory settings to characterize patient specimens and / or to detect, identify, classify, classify and / or characterize specific organisms , antibiotic susceptibility and / or the li...

Abstract

The invention relates to equipment, and the equipment includes a housing that defines a fluid reservoir and includes a port that is in fluid communication with the fluid reservoir. An inlet adapter is removably coupleable to the housing. A user can engage an actuator to move a plunger from a first position in which the fluid reservoir has a first volume, to a second position in which the fluid reservoir has a second volume greater than the first volume, which draws bodily fluid into the fluid reservoir via the inlet adapter. The actuator modulates a plunger rate of motion below a threshold as the plunger is moved. When a predetermined volume of bodily fluid is transferred into the fluid reservoir, a volume indicator transitions from a first state to a second state and the inlet adapter can then be removed to transfer the predetermined volume into a sample bottle external to the housing via the port.
