問題一覧

Amniotic fluid is found inside the amniotic sac known as which surrounds the fetus

AMNION

Metabolically active which helps exchange water in chemicals between the fluid and the mother's blood

AMNION

Main function is to protect the fetus by acting execution and allowing free movement

AMNIOTIC SAC

Amniotic fluid increases during pregnancy which peaks how many ml in the third trimester

800-1,200

How many ml of amniotic fluid in the first trimester

This refers to too much amniotic fluid

POLYHYDRAMNIOS

This refers to too little amniotic fluid

OLIGOHYDRAMNIOS

What is the main source of amniotic fluid

PLACENTA

Select all sources of amniotic fluid

FETAL URINE, FETAL RESPIRATORY SECRETION, AMNIOTIC MEMBRANE, UMBILICAL CORD

Amniotic fluid is similar to

MATERNAL PLASMA

Amniotic fluid contains___which from skin digestive and urinary tract that is used for genetic testing

FETAL CELLS

Creatinine in the amniotic fluid indicates

FETAL AGE, KIDNEY DEVELOPMENT

Normal creatinine amniotic fluid before 36 week

1.5-2.0 MG/DL

Normal creatinine amniotic fluid after 36 week

>2.0 MG/DL

Help doctors tosses when fetus is mature enough for delivery

CREATININE

Used to help determine if there has been a possible premature rupture of membranes or an accidental puncture of the mother's bladder during specimen collection

MATERNAL URINE

Amniotic fluid is similar to

URINE, PERICARDIAL FLUID

Creatinine: <3.5 mg per dl

AMNIOTIC FLUID

Creatinine: >10 mg per dl

URINE

Urea: <30 mg per dl

AMNIOTIC FLUID

Urea: >300 mg per dl

URINE

Glucose and Protein: +

AMNIOTIC FLUID

Glucose and Protein: -

URINE

Creatinine levels in the amniotic fluid during late pregnancy can be___higher than normal plasma level

2-3X

This is creatinine level in amniotic fluid against normal plasma level which may indicate that the sample is urine or amniotic fluid contaminated with urine

>4 MG/DL

Microscopic test that helps differentiate amniotic fluid from other body fluids

FERN TEST

A positive result shows fern like crystals during fern test because of the

SODIUM CHLORIDE, PROTEIN

Amniotic fluid is collected by inserting a needle into the amniotic sac—this procedure is called

AMNIOCENTESIS

The most common method is of amniocentesis is

TRANSABDOMINAL

Maximum volume of amniocentesis collected

30 ML

How many ml of amniotic fluid should be discarded first

2-3 ml

Amniocentesis is usually done at what week

15th

Storage temperature for amniotic fluid for Fetal lung maturity

REFRIGERATOR

The sample amniotic fluid must be protected from___for bilirubin testing

LIGHT

Storage temperature for amniotic fluid for Cytogenetic or microbial studies

BODY TEMPERATURE

Normal color of amniotic fluid

COLORLESS, TURBID

May be due to traumatic tap,abdominal tap, or intra-amniotic hemorrhage

BLOOD STREAKED

test to findout if the blood is from the motheror fetus

KLEIHAUER BETKE TEST

May indicate presence of bilirubin

YELLOW, AMBER

Associated with fetal distress and risk of meconium aspiration

DARK GRAY

Indicates blood contamination

PINK-RED

Suggests fetal death Requires urgent medical attention

DARK REED BROWN

Provides fetal skin during development

VERNIX

Tests for Neural Tube Defects Markers:

AFP, AChe

Normal mOsm of AFP

0.5-2.5

Refers to signs that appear before orduring childbirth showing that the fetus is not doing well, usually because it is not getting enough oxygen.

FETAL DISTRESS

Monitors fetal heart rate in response to fetal movement

NON STRESS TEST

Monitors the fetal heart during induced contractions.

CONTRACTION STRESS TEST

Assesses how well blood flows through the umbilical artery.

DOPPLER FLOW STUDY

It checks the pH level of fetal blood during labor

FETAL SCALP BLOOD SAMPLING

Normal pH amniotic fluid

>7.25

Detects fetal anemia due to hemolysis Uses a spectrophotometric scan to measure

BILIRUBIN

Interpretation of bilirubin in amniotic fluid

LILEYS CHART

Mild or no disease in bilirubin amniotic test

ZONE1

High risk of hydrops, may require early delivery or transfusion.

ZONE3

Used to screen for Neural tube defects (NTDs)

AFP

Used to confirm open neural tube defects.

ACHE

Most common complication of premature delivery and life-threatening for premature infants. Due to immaturity of the fetal lungs leading to insufficient production of lung surfactant

Respiratory Distress Syndrome

Structures composed of phospholipidlayers and serve as the storage form of pulmonarysurfactant. It also releases surfactant into the alveolar spaces that appear in amniotic fluid around 26 weeks of pregnancy.

Lamellar Bodies

Optical Density centrifuged setting

2000g/10 min

The reference method where FLM tests are compared to.

Lecithin/Sphingomyelin (L/S) Ratio

Major lung surfactant

LECITHIN, PHOSPHATIDYLCHOLINE

A phospholipid that helps surfactants spread across the surface of the alveoli in the lungs

Phosphatidylglycerol

A protein produced by the fetus. Peaks around 16 weeks of pregnancy, then declines gradually.

AFP

Indicates fetal distress during fetal non stress test

NON REACTIVE

Indicates fetal distress during contraction stress test

LATE DECELERATIONS

Suggests open NTD (e.g., spina bifida), gastroschisis, or twins of AFP in amniotic fluid

High AFP

May suggest Down syndrome of AFP in amniotic fluid

LOW AFP

A substance that allows the alveoli toremain open by reducing the surface tension. Prevents the alveoli from collapsing during exhalation and allows air to enter easily during inhalation.

Surfactant

Falsely decreases the count of Lamellar Bodies

Blood

Causes minimal increase in counts in lamellar bodies

Meconium

Agglutination of PG using Polyclonal anti-PG antibodies; qualitative results.

AGGLUTINATION TEST

Phosphatidylglycerol confirmatory test
