I want to have a paternity test in Jining. Is there a formal appraisal center?

Paternity appraisal must be conducted in the local judicial appraisal institution. For details, please consult the local judicial bureau or the provincial judicial department, or consult the directory of local formal judicial authentication institutions in official website.

Primitive method

Appearance contrast

Due to genetic reasons, father and son, mother and son, brothers and sisters have some similarities in appearance and skin color. It is probably the most primitive method to determine the parent-child relationship through the comparison of appearance and appearance, but this method is only a guess and judgment for reference.

Bone loss test relatives.

The method of bone drop test is to drop the blood of the living on the bones of the dead. If blood can penetrate into the bone, it is concluded that there is a blood source relationship between the living and the dead, otherwise there is no blood source. The Biography of the Sages in Huiji, written by Xie Cheng, a Wu native during the Three Kingdoms period, records the case of using the blood of the younger brother to hold the bone of the older brother. (The Biography of Nan Shi Wang Yuzhang also records the test of relatives with his son's blood dripping on his father's bones; Song Ci, a famous forensic scientist in the Song Dynasty, included the method of testing relatives by breaking bones in the Collection of Injustice. From a modern point of view, this method is not scientific, but it is the first to use blood type to identify the relationship between blood sources.

Drop blood to test relatives

Blood test, also known as blood test, is to put a child's blood and an adult's blood together. If they can blend together, they are the parents' own, otherwise they are not. This method of sample identification was recorded in China's forensic works in Song Dynasty. This method has no scientific basis. The blood of parent-child relationship may not be merged, and the blood of non-parent relationship may be merged.
