Question

In context of Amniocentesis, which of the following statement is incorrect?

K SUNKANNA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Amniocentesis
	**Related Topics**: Prenatal Diagnosis, Genetic Testing, Pregnancy
	**Prerequisites**: Basic understanding of pregnancy and genetic testing.
## SOLUTION PATHWAY
**Given Information**:
	The question asks for the INCORRECT statement about amniocentesis.
**Method & Steps**:
	1. **Understanding Amniocentesis:** Amniocentesis is a prenatal diagnostic test used to detect chromosomal abnormalities and other genetic conditions in a fetus.
		Reasoning: It involves extracting a small amount of amniotic fluid, which contains fetal cells.
	2. **Timing of Amniocentesis:** Amniocentesis is typically performed between 15 and 20 weeks of gestation, not 10-12 weeks.
		Working: Performing the procedure earlier carries a higher risk of complications.
		Key Point:  Chorionic villus sampling (CVS) is another prenatal test that can be performed earlier, between 10 and 13 weeks.
	3. **Risks and Procedure:** Amniocentesis carries a small risk of miscarriage and involves inserting a needle through the abdomen into the uterus.
		Result: Option A is the incorrect statement.
		Verification: Other options correctly describe aspects of amniocentesis.
 ## OPTION ANALYSIS
[A] :x: **Typically performed between 10-12 weeks of gestation:** This is incorrect. Amniocentesis is typically performed between 15-20 weeks of gestation.
[B] ✓: **Used to detect chromosomal abnormalities:** This is correct.  Amniocentesis is used to detect chromosomal abnormalities like Down syndrome.
[C] ✓: **Carries a small risk of miscarriage:** This is correct. Although rare, miscarriage is a potential complication.
[D] ✓: **Involves inserting a needle through the abdomen into the uterus:** This is correct. This is how the amniotic fluid sample is obtained.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing Amniocentesis with CVS:  CVS is performed earlier in pregnancy (10-13 weeks).
			How to avoid: Remember the different timeframes for these two procedures.
		2.  Overestimating the risk of miscarriage: While there is a risk, it is generally considered small (less than 1%).
			How to avoid: Understand that the risk is relatively low but still present.
	**Quick Tips**:
		1. **'Amnio' relates to amniotic fluid':** This can help remember what the procedure involves.
		2. **'Second Trimester Test':**  Remembering that amniocentesis is typically performed in the second trimester can help differentiate it from CVS.
