The cost of a breast milk test is about 100-200 RMB. Through the breast milk test, we can find out if a woman is suffering from breast inflammation, breast enlargement, hepatitis B virus, etc. Many women have germs in their breast milk, which can easily be transmitted to their children through breast milk, causing the children to be infected with certain bacteria and viruses. If the transmission is not cut off in time, it is easy to cause recurring attacks. The cost of breast milk testing is not particularly expensive, but the cost is affected by the price, medical level, economic level and other aspects, so the cost may fluctuate, but it is within the reach of the average person.
