The blood test, which brides and grooms take before they are allowed to take out a marriage license, are to determine whether or not either party has syphilis and gonorrhea. These test have never tested for positive/negative blood types nor inherited diseases.
Those two can cause birth defects, if not, syphilis DOES cause insanity and death if not treated.
These test have never tested for positive/negative blood types nor inherited diseases.
You are wrong, doctors DO test blood types for that reason. I know that for a fact from about medical professionals who told me so DIRECTLY.
And those tests have not been a requirement for a marriage license in Texas for at least 20 or 30 years.
