as lengths widths and diameters of the sections of system 1300 can be configured to adjust for different volumes flow rates or other parameters fig2 depicts channel 1308 with diameter d7 analysis chamber 1310 with diameter d8 and channel 1312 with diameter d9 in certain approaches diameters d7 d8 and d9 are each approximately the same to provide an even flow into and through analysis chamber 1310 in certain approaches diameters d7 d8 and d9 have different sizes to accommodate for different flow rates the addition of reagents or removal of portions of the sample in certain approaches the systems devices and methods described herein are used for diagnosing a disease in a human the systems devices and methods may be used to detect bacteria viruses fungi prions plant matter animal matter protein rna sequences dna sequences cancer genetic disorders and genetic traits for example the disorder chlamydia is a bacterial disease caused by the bacteria chlamydia trachomatis a caretaker such as a nurse or physician may obtain a sample from a patient desiring to receive a diagnosis for this disorder for example the caretaker may use a medical swab to wipe a surface of the vagina to thereby obtain a biological sample of vaginal fluid and vaginal epithelial cells if the patient is carrying the chlamydia trachomatis bacteria the bacteria would be present in the sample additionally markers specific to the human.
