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?
No, red blood cells (RBCs) do not have a nucleus or organelles and do not contain DNA. White blood cells (WBCs) do contain DNA because they have a nucleus.
Which blood cell has DNA?
All blood cells have DNA, which carries genetic information and is important for cell functions. White blood cells, red blood cells, and platelets all contain DNA, although red blood cells lose their nucleus during maturation and do not have a nucleus with DNA.
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.
Can you use menstrual blood to take a blood type test?
No, menstrual blood is not suitable for blood type testing. It does not provide accurate results as it may contain various other substances that can interfere with the test. It is recommended to use a blood sample obtained through a traditional venipuncture method for accurate blood type testing.

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?
Yes, mammalian blood contains DNA from the cells it carries. White blood cells, which are part of the immune system, contain DNA, and when they break down, the DNA is released into the blood. This can be useful in forensic investigations or medical diagnostics.
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.
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?
No, DNA testing requires a white blood cell sample because red blood cells do not have a nucleus, which is necessary for DNA analysis. White blood cells contain a nucleus where DNA is located, making them suitable for DNA testing.
Is every biological sample being DNA evidence?
No, When we considering the human blood reb blood cells don't contain neclues. So in red blood cells they don't contain DNA. So it's not a DNA evidence.(Red blood cells). Not only them hair without roots, nails with out mussels are other examples.
