Can baking soda produce a negative result on urinalysis?

Yes, baking soda can affect the results of a urinalysis. Baking soda is a base and can alter the pH of urine. Changes in urine pH can affect the solubility and concentration of various substances, such as proteins, glucose, and ketones, which can lead to inaccurate results. Baking soda can also react with certain chemicals used in urine test strips, causing false positive or false negative results. Therefore, it is important to inform your healthcare provider if you have consumed baking soda or any other substance that may interfere with a urinalysis before providing a urine sample.
