Disclosed herein are systems and methods for analyzing failed bodily fluid sampling. The systems and methods include providing a system having a sampling line and an access device, the access device having an inner space, wherein the sampling line is positioned in the inner space performing a sampling event obtaining one or more status values of the sampling event comparing the one or more status values with at least one predetermined value corresponding to a failed sampling event and determining whether the sampling event failed based on the comparing step. In the event of sampling failure, the systems and methods provide flushing the sampling line or a portion of the inner space of the access device via the flow controller detecting pressure and determining one or more possible root causes for the failure of the sampling event based on the detected pressure.
