86910 Blood typing, for paternity testing, per individual; ABO, Rh and MN

Name of the Procedure:

Blood Typing for Paternity Testing; ABO, Rh, and MN

Summary

Blood typing for paternity testing involves analyzing the blood of individuals to determine their ABO, Rh, and MN blood group types. This information can help establish biological parentage.

Purpose

Blood typing for paternity testing is used to determine the biological relationship between an alleged parent and a child. The expected outcome is to either confirm or exclude an individual as the biological parent based on blood group compatibility.

Indications

• Doubts about paternity or family history.
• Legal cases requiring paternity proof.
• Personal or family reasons for confirming biological relationships.

Preparation

• No special preparation is typically necessary for blood typing.
• Inform the healthcare provider of any medications or health conditions that might affect blood test results.

Procedure Description

1. A healthcare professional will clean the site, usually an arm vein.
2. A blood sample is drawn using a sterile needle and collected in a tube.
3. The blood is sent to a laboratory for analysis.
4. In the lab, technicians test the blood sample for ABO, Rh, and MN antigens.
5. Results are compared between individuals to determine potential biological relationships.

Duration

The blood draw takes about 5-10 minutes. Laboratory analysis might take several days to a week.

Setting

The blood sample is typically drawn in a hospital, outpatient clinic, or specialized laboratory.

Personnel

• Phlebotomist or nurse to draw blood.
• Laboratory technicians to analyze the samples.
• A physician or genetic counselor may interpret the results.

Risks and Complications

• Common: Minor bruising or discomfort at the needle site.
• Rare: Infection at the needle site, fainting, or dizziness.
• No significant complications associated with the laboratory analysis itself.

Benefits

• Provides crucial information about biological relationships.
• Results can clarify legal, personal, and medical inheritance issues.
• Typically, results are reliable and available within a week.

Recovery

• Very minimal recovery is needed since the procedure involves just a simple blood draw.
• Patients can usually resume normal activities immediately.

Alternatives

• DNA testing is a more definitive method for paternity testing and offers a higher accuracy rate.
• Pros of blood typing: less expensive and simpler than DNA testing.
• Cons of blood typing: less accurate and conclusive than DNA testing.

Patient Experience

• During the blood draw: mild discomfort or a pinch when the needle is inserted.
• Post-procedure: Possible minor bruising or tenderness at the draw site.
• Pain management: Generally, no pain relief is needed; over-the-counter medications like acetaminophen can be used if necessary.
