Attempt the Quiz - Diagnostic Techniques

Here are a few simple Quiz questions that relate to Diagnostic Techniques from the practical.

1 Which of the following options would be the earliest invasive diagnostic technique carried out clinically:

	none of the above

2 Which placental parameter is measured by ultrasound at the mid-portion from the chorionic plate to the basilar plate.

	placental diameter
	placental thickness
	placental volume

	up to 8 weeks
	8 to 13 weeks
	13 to 21 weeks
	21 to 33 weeks
	34 weeks
	40 weeks

5 Cord stem cells can be derived from which of the following tissues:

	placental cord blood

	maternal placental tissue
	all of the above
	none of the above

6 Which of the following diagnostic techniques has in the past identified as having the higher risk for miscarriage?

	ultrasound
	amniocentesis
	chorionic villus sampling
	fetal cells from maternal blood
