84112 Evaluation of cervicovaginal fluid for specific amniotic fluid protein(s) (eg, placental alpha microglobulin-1 [PAMG-1], placental protein 12 [PP12], alpha-fetoprotein), qualitative, each specimen

Name of the Procedure:

Evaluation of Cervicovaginal Fluid for Specific Amniotic Fluid Proteins (e.g., Placental Alpha Microglobulin-1 [PAMG-1], Placental Protein 12 [PP12], Alpha-Fetoprotein), Qualitative, Each Specimen

Summary

This procedure involves analyzing samples of cervicovaginal fluid to detect specific proteins that are typically found in amniotic fluid. This can help determine if there is leaking of amniotic fluid, which may indicate premature rupture of membranes (PROM) during pregnancy.

Purpose

The procedure is primarily used to diagnose conditions involving the leakage of amniotic fluid, such as PROM. Identifying these specific proteins can confirm the presence of amniotic fluid, indicating a tear or rupture in the amniotic sac.

Indications

• Symptoms such as a sudden gush or slow leak of fluid from the vagina during pregnancy
• Suspected premature rupture of membranes (PROM)
• Pregnant women experiencing unexplained vaginal wetness

Preparation

• The patient may be asked to refrain from using any vaginal medications, douches, or having sexual intercourse for 24 hours before the test.
• No specific fasting or medication adjustments are usually required.
• A pelvic exam may be conducted beforehand.

Procedure Description

1. The patient lies down in a comfortable, supine position.
2. A speculum is gently inserted into the vagina to visualize the cervix.
3. Using a sterile swab or collection device, a sample of cervicovaginal fluid is obtained.
4. The sample is then sent to a laboratory, where it is tested for the presence of specific amniotic fluid proteins (PAMG-1, PP12, alpha-fetoprotein).
5. The results are interpreted qualitatively to confirm whether amniotic fluid is present.

Duration

The procedure itself typically takes about 10-15 minutes.

Setting

This procedure is usually performed in an outpatient clinic or an obstetrician's office.

Personnel

• Obstetrician-gynecologist (OB-GYN)
• Nurse or medical assistant

Risks and Complications

• Minimal risk of discomfort or minor irritation during sample collection
• Very rare risk of infection
• False-positive or false-negative results, requiring additional investigation

Benefits

• Accurate diagnosis of premature rupture of membranes (PROM)
• Enables timely and appropriate medical interventions to manage pregnancy complications
• Helps ensure the safety and health of both the mother and baby

Recovery

• No significant recovery time needed.
• The patient can usually resume normal activities immediately after the procedure.
• Follow-up appointments may be scheduled if the test results indicate PROM.

Alternatives

• Observation and symptom monitoring
• Amniocentesis in uncertain cases
• Ultrasound examination to assess amniotic fluid levels and fetal well-being

Patient Experience

• The patient might feel mild discomfort or pressure during the speculum insertion and sample collection.
• After the procedure, there may be a slight spotting or sensation of wetness, but this is generally minimal and temporary.
• Pain management is generally not necessary, but if discomfort occurs, over-the-counter pain relievers can be taken.
