A device (10) for determining the amount or concentration of an analyte (1700) in a fluid sample (1500) and a flow rate (1000) of the fluid sample (1500) in a channel (14) is provided. The device (10) includes a chamber (20) including a channel (14) and an opening (12a), the channel (14) in fluid communication with the opening (12a). The device further includes a wicking component (16) positioned adjacent to the opening (12a) configured to receive an amount of fluid (1500) from the channel (14). The device may further include an analyte sensor (18) positioned on the wicking component (16), the analyte sensor (18) configured to detect an analyte (1700) in fluid ((1500) in contact with the analyte sensor (18), wherein the wicking component (16) is configured to contact the amount of fluid (1500) with the analyte sensor (18). Alternatively the device (10) may include at least one pair of electrodes (130, 132) configured to determine a flow rate (1000) of the fluid (1500) in the channel (14).
