Actually sometimes women DO. An obvious case is where someone else like the state doubts paternity- such as believing a child might be kidnapped etc. Another somewhat obvious one is in cases where the parents either have reason to suspect- or are just extra cautious of the possibility a child was “switched at birth.” While this is VERY rare in most countries (in the US only about 28,000 babies out of around 4 million a year reportedly get switched- and it is usually temporary- such as an administrative mix up in the nursery or while doing tests etc- in a way the parents never even know it happened) some people like to be sure.

That said- while modern DNA testing can offer very accurate results on if someone is the parent of a child with only one parent- sometimes there is a DNA mutation (usually with the father) that requires the mothers DNA be used in testing as well to ensure accuracy. In general- accuracy can be improved by testing both parents against a child (many home tests will do this to increase odds of accurate results since they can be less accurate because of their nature or because for the price point less accurate or older test methods are used.)

Now- OBVIOUSLY 99.99% of the time you don’t need a test to tell you a woman was pregnant or delivered a baby provided that she was either getting regular medical care or you witnessed the event- and generally simple organization and practicality makes Matching a mother to her child a matter of just remembering where you put the baby that just came out of her. BUT- there are pocket cases that do require a mother be DNA tested for paternity- sometimes to determine her own paternity to the child. Just as some fun facts.
