Dipper Urinalysis Dipstick ControlMonitor the performance of visual and instrument readings of urinalysis dipsticks by immersing the dipstick into the control the same way you test your patient samples. We include values for all dipstick analytes plus microalbumin and creatinine, and qualitative results for hCG early pregnancy detection test methods. Dipper Urinalysis Dipstick Control is designed for use with most urinalysis reagent strips. It can also be used for confirmatory tests and refractometry.
