This disclosure provides an impedance cytometer which includes a carrier that can be attached to a living being, with a biosensor mounted thereto. The bio sensor includes a microfluidic flow channel, formed in the carrier, and an impedance circuit. The microfluidic flow channel accommodates passage of a particle therethrough. The impedance circuit, connected to the microfluidic flow channel, includes a signal generator that produces a high-frequency drive signal applied to the flow channel to produce a biosensor output signal having high-frequency variation resulting from the drive signal and low-frequency variation resulting from impedance variation within the flow channel during the particle's passage. A lock-in amplifier is disposed to (i) amplify the bio sensor output signal, (ii) mix the amplified signal with the drive signal, and (iii) frequency-filter the mixed, amplified signal to output an impedance signal representing the low-frequency impedance variation resulting from the passage of the particle. Embodiments enable wearable, personalized cytometry.

The principles and embodiments of the present disclosure relate to methods for using terlipressin to treat a patient having impaired renal function associated with liver disease. A method of improving kidney function in an adult patient with hepatorenal syndrome with rapid reduction in kidney function may include determining the patient’s acute-on-chronic liver failure (ACLF) grade and baseline serum creatinine level; obtaining a baseline oxygenation saturation (SpO.sub.2) of the patient; administering a dose of terlipressin acetate to the patient by intravenous (IV) injection; and monitoring the patient’s oxygenation saturation with pulse oximetry.

A blood cell analysis method and a blood cell analyzer are provided.
