Gestational Diabetes Mellitus (GDM) Test

The 2-Step Procedure for Screening and Diagnosis of Gestational Diabetes Mellitus (ADA) is done to identify individuals who have gestational diabetes, which is a type of diabetes that develops during pregnancy.

Here are the reasons why the 2-step procedure for Gestational Diabetes Mellitus (GDM) screening and diagnosis is done:

• The initial GCT is a simpler test, requiring less preparation and reducing burden on patients.
• GCT effectively identifies women at higher risk for GDM based on their blood sugar response to the glucose challenge.
• Reduces unnecessary testing: Women with normal GCT results likely don't require the more complex and time-consuming OGTT.
• Confirms diagnosis: OGTT provides a definitive diagnosis for women with high GCT results, allowing for proper management of GDM.

The 2-Step Procedure for Screening and Diagnosis of Gestational Diabetes Mellitus (ADA) is typically recommended for all pregnant individuals. However, there are certain individuals who are at higher risk for gestational diabetes and may be more likely to benefit from the screening and diagnosis. The American Diabetes Association (ADA) recommends that all pregnant individuals be screened for gestational diabetes between 24-28 weeks of pregnancy, but some individuals may need to be screened earlier or more frequently based on their risk factors.

Risk factors for gestational diabetes include:

• Obesity
• Previous diagnosis of gestational diabetes
• Family history of diabetes
• Previous delivery of a large baby
• A history of impaired glucose tolerance or impaired fasting glucose
• A history of polycystic ovary syndrome (PCOS)

It's important to note that even if a person does not have any risk factors, gestational diabetes can still occur, that's why the screening is recommended for all pregnant individuals.

The 2-Step Procedure for Screening and Diagnosis of Gestational Diabetes Mellitus (ADA) measures blood sugar levels in pregnant individuals to identify those who have gestational diabetes.

This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer.

If the 2-Step Procedure for Screening and Diagnosis of Gestational Diabetes Mellitus (ADA) tests positive, it indicates that the individual has gestational diabetes. This means that the individual has high blood sugar levels during pregnancy. It is important for individuals with gestational diabetes to work closely with their healthcare provider to manage their blood sugar levels and reduce the risk of complications for themselves and their baby. This may include following a healthy diet, regular physical activity, and potentially taking medication to manage blood sugar levels.

The gestational diabetes mellitus (GDM) test is a series of blood tests used to diagnose high blood sugar levels in pregnant women.

Yes, Metropolis Healthcare offers a convenient home sample collection service for the GDM test, ensuring comfort and safety for pregnant women. A trained phlebotomist will visit your doorstep to collect the necessary blood samples, maintaining high standards of sample handling and testing accuracy.

Normal ranges for the GDM test are below the following thresholds: fasting <95 mg/dL, 1 hour <180 mg/dL, 2 hours <155 mg/dL, and 3 hours <140 mg/dL.

All pregnant women, especially those with risk factors like obesity, family history of diabetes, or previous GDM.

The benefits of the GDM test include early detection and management of gestational diabetes, prevention of adverse pregnancy outcomes, and long-term health monitoring for the mother and child.

Typically, the GDM test is performed once between the 24th and 28th weeks of pregnancy, unless high-risk factors warrant earlier testing.

The GDM test is usually done in the morning, after fasting for at least 8 hours.

Yes, fasting for at least 8 hours is required for the GDM test.

Yes, avoid smoking, remain seated, and discontinue nonessential medications that affect glucose metabolism.

The parameters included in the GDM test are fasting blood glucose and 1-hour, 2-hour, and 3-hour blood glucose levels.

The GDM test involves consuming a glucose-containing liquid and having blood drawn at specified intervals to measure blood glucose levels.

The GDM test is typically performed between the 24th and 28th weeks of pregnancy. However, if you have high-risk factors such as obesity, family history of diabetes, or previous GDM, your doctor may recommend earlier testing.

The GDM test becomes positive when two or more blood glucose values exceed the specified thresholds: fasting ≥95 mg/dL, 1 hour ≥180 mg/dL, 2 hours ≥155 mg/dL, or 3 hours ≥140 mg/dL.

The GDM test takes approximately 3 hours to complete.

The turnaround time for the GDM test reports may vary depending on the diagnostic lab and the city you are in. However, most labs provide the results within 24 hours based on the gay/time of sample collection. It is best to check with your doctor or the diagnostic centre for a more accurate estimate of when you can expect your reports.
