Yes, menstrual blood will contain DNA of the individual who is menstruating (also possible DNA from sexual partners if they had sex within a few days of taking the sample). Menstrual flow contains blood, tissue, discharge, cervical mucus, and skin cells which all will contain DNA.

How valuable are red blood cells in DNA typing?
Red blood cells do not contain a nucleus, which means they lack DNA. As a result, red blood cells are not useful for DNA typing. Instead, white blood cells, which do contain DNA, are typically used for DNA profiling and typing in forensic analysis.
Is DNA found in RBC and WBC?
You have about 25 trillions of RBC in your blood. They do not have nucleus in them and so no DNA. WBC has a nucleus and contains the DNA.
Which blood cell has DNA?
All groups of white blood cells have DNA. When a blood sample is procured for the isolation of DNA, the white blood cells are the target cells since they have nuclei containing DNA. Red blood cells on the other hand, contain neither nuclei nor DNA
How does the composition and function of menstrual blood differ from that of regular blood?
Menstrual blood is a mixture of blood and tissue shed from the uterus during menstruation, while regular blood is primarily composed of red blood cells, white blood cells, platelets, and plasma. Menstrual blood may also contain cervical mucus and endometrial tissue. The function of menstrual blood is to shed the uterine lining, while regular blood circulates oxygen and nutrients throughout the body and helps remove waste products.
What is the source of DNA in blood?
DNA in blood comes from white blood cells, which contain the person's genetic information. When blood is collected for testing or analysis, the DNA can be extracted from these cells to study and identify specific genetic markers or sequences.

Which human body parts don't contain DNA example do our skin and nail contain DNA?
Red blood cells
Do any cells contain less or no DNA content?
Yes, there is one type of cell which does not contain DNA, and that is the red blood cell.
Does mammalian blood contain any DNA?
White blood cells carry genetic information. In mammals mature red blood cells do not have DNA because they do not have nuclei. They expel them during the maturation process. However, in birds and reptiles they have nucleated red blood cells. Thus reptile and bird red blood cells do contain DNA.
What of your body's cells contain DNA?
red blood cells
Would you expect to get a positive DNA test in a mature red blood cell?
No, mature red blood cells do not contain a nucleus or DNA. They lose their DNA as they mature to better accommodate their main function of carrying oxygen. Therefore, a DNA test on a mature red blood cell would be negative.
What part of the blood sample should be used for the DNA analysis and why?
For DNA analysis, the white blood cells (leukocytes) in the blood sample are typically used because they contain a nucleus, which houses the DNA. Red blood cells, on the other hand, do not have nuclei and therefore do not contain DNA. Platelets also lack DNA, making leukocytes the preferred choice for extracting high-quality genetic material for analysis.
Why erythrocytes cannot be used in DNA fingerprinting?
Erythrocytes, or red blood cells, do not contain a nucleus and therefore do not contain DNA. Since DNA fingerprinting relies on analyzing the unique genetic information found within the nucleus of cells, erythrocytes are not suitable for this purpose. Other cell types like white blood cells are typically used in DNA fingerprinting because they contain a nucleus with DNA.
Why do frog blood cells contain DNA while human blood cells don't?
Not true. They both do. DNA is contained in all living cells.
Can DNA testing be carried out on red blood cells alone?
It depends on the organism you're talking about and what kind of DNA. A mammilial red cell does not have nucleus, so most DNA testing is impossible. However, it does have mitochondria, which contain their own DNA, and testing can be done on this.
