Abo Group

Absolute Band Neutrophils

Immature forms of neutrophils are called neutrophilic band cells. Neutrophils are a type of white blood cell that is responsible for much of the body's protection against infection. Neutrophils are produced in the bone marrow and released into the bloodstream to travel to wherever they are needed. Large numbers of immature forms of neutrophils, called neutrophilic band cells, are produced by the bone marrow when the demand is high.

Absolute Basophils

Basophils normally constitute 1% or less of the total white blood cell count but may increase or decrease in certain diseases and are thought to be involved in allergic reactions.

Absolute Blasts

Blasts are immature forms of white blood cells.

Absolute Eosinophils

Eosinophils (eos) respond to infections caused by parasites and play a role in allergic reactions (hypersensitivities)

Absolute Lymphocytes

Lymphocytes are white blood cells that exist in both the blood and the lymphatic system. They are divided into three types. The B lymphocytes (B cells) are antibody-producing cells that are essential for acquired, antigen-specific immune responses. The second type are T lymphocytes (T cells) some T cells help the body distinguish between "self" and "non-self" antigens while others initiate and control the extent of an immune response, boosting it as needed and then slowing it as the condition resolves. Other types of T cells directly attack and neutralize virus-infected or cancerous cells. The third type are natural killer cells (NK cells) that directly attack and kill abnormal cells such as cancer cells or those infected with a virus.

Absolute Metamyelocytes

Metamyelocytes are immature forms of white blood cells.

Absolute Monocytes

Monocytes (mono), similar to neutrophils, move to an area of infection and engulf and destroy bacteria. They are associated more often with chronic rather than acute infections. They are also involved in tissue repair and other functions involving the immune system.

Absolute Myelocytes

Myelocytes are immature forms of white blood cells.

Absolute Neutrophils

Neutrophils (neu) normally make up the largest number of circulating WBCs. They move into an area of damaged or infected tissue, where they engulf and destroy bacteria or sometimes fungi. Young neutrophils, recently released into circulation, are called bands.

Absolute Nucleated Rbc

Nucleated Red Blood Cells (nRBC) ) the presence of NRBCs in the adult blood is usually associated with malignant neoplasms, bone marrow diseases, and other serious disorders.

Absolute Promyelocytes

Promyelocytes are immature forms of white blood cells.

Hematocrit

Hematocrit is a blood test that measures the percentage of the volume of whole blood that is made up of red blood cells. This measurement depends on the number of red blood cells and the size of red blood cells.

Hemoglobin

Serum hemoglobin is a blood test that measures the level of free hemoglobin in the liquid part of the blood (the serum). Free hemoglobin is the hemoglobin outside of the red blood cells. Most of the hemoglobin is found inside the red blood cells, not in the serum.

The third type are natural killer cells (NK cells) that directly attack and kill abnormal cells such as cancer cells or those infected with a virus.

MCH

Mean corpuscular hemoglobin (MCH) is a calculation of the average amount of oxygen-carrying hemoglobin inside a red blood cell.

MCHC

Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average percentage of hemoglobin inside a red cell.

MCV

Mean corpuscular volume (MCV) is a measurement of the average size of RBCs.

Metamyelocytes

Metamyelocytes are immature forms of white blood cells.

Monocytes

Monocytes (mono), similar to neutrophils, move to an area of infection and engulf and destroy bacteria. They are associated more often with chronic rather than acute infections. They are also involved in tissue repair and other functions involving the immune system.

MPV

Mean Platelet Volume (MPV) - When it indicates average size of platelets are small; older platelets are generally smaller than younger ones and a low MPV may mean that a condition is affecting the production of platelets by the bone marrow. When it indicates a high number of larger, younger platelets in the blood; this may be due to the bone marrow producing and releasing platelets rapidly into circulation.

Myelocytes

Myelocytes are immature forms of white blood cells.

Neutrophils

Neutrophils are a type of white blood cell that is responsible for much of the body's protection against infection. Neutrophils are produced in the bone marrow and released into the bloodstream to travel to wherever they are needed.

Nucleated Rbc

Nucleated Red Blood Cells (nRBC) ) the presence of NRBCs in the adult blood is usually associated with malignant neoplasms, bone marrow diseases, and other serious disorders.

Platelet Count

A platelet count is a test to measure how many platelets you have in your blood. Platelets help the blood clot. They are smaller than red or white blood cells.

Promyelocytes

Promyelocytes are immature forms of white blood cells.

RDW

Red cell distribution width (RDW), which may be included in a CBC, is a calculation of the variation in the size of RBCs.

Reactive Lymphocytes

Lymphocytes are white blood cells that exist in both the blood and the lymphatic system. They are divided into three types. The B lymphocytes (B cells) are antibody-producing cells that are essential for acquired, antigen-specific immune responses. The second type are T lymphocytes (T cells) some T cells help the body distinguish between "self" and "non-self" antigens while others initiate and control the extent of an immune response, boosting it as needed and then slowing it as the condition resolves. Other types of T cells directly attack and neutralize virus-infected or cancerous cells. The third type are natural killer cells (NK cells) that directly attack and kill abnormal cells such as cancer cells or those infected with a virus.

Red Blood Cell Count

An RBC count is a blood test that tells how many red blood cells (RBCs) you have. RBCs contain hemoglobin, which carries oxygen. How much oxygen your body tissues get depends on how many RBCs you have and how well they work.

When and Why the Test May Be Ordered:

The Obstetric Panel test is typically ordered during the early stages of pregnancy, often during the first prenatal visit. It may also be repeated at different points throughout the pregnancy to monitor the health of both the pregnant person and the fetus. The primary objective is to detect any potential risks or complications that could affect the pregnancy or the health of the individuals involved.

What the Test Checks For:

The Obstetric Panel test assesses several key parameters:

  1. Blood Type and Rh Factor: Determines the blood type and Rh factor of the pregnant individual, which is crucial for preventing Rh incompatibility issues between the mother and the fetus.
  2. Complete Blood Count (CBC): Measures red blood cells, white blood cells, and platelets, helping to identify anemia or infections.
  3. Rubella Antibodies: Checks for immunity to rubella (German measles) to prevent complications in case of exposure.
  4. Hepatitis B Surface Antigen: Identifies if the pregnant person is a carrier of hepatitis B virus, which can be transmitted to the baby during childbirth.
  5. Syphilis Test: Screens for syphilis, a sexually transmitted infection that can affect both the pregnant individual and the fetus.

Other Lab Tests That May Be Ordered Alongside:

Here are some common tests that are often ordered alongside routine obstetric care and the reasons for each:

  1. Complete Blood Count (CBC):

    • Purpose: To evaluate overall blood health.
    • Why Is It Ordered: To check for anemia, a common condition in pregnancy, and to monitor white blood cells and platelets.

  2. Blood Type and Rh Factor:

    • Purpose: To determine the mother's blood type and Rh factor.
    • Why Is It Ordered: To identify potential Rh incompatibility between mother and fetus, which can lead to complications like hemolytic disease of the newborn.

  3. Urinalysis:

    • Purpose: To analyze components of the urine.
    • Why Is It Ordered: To screen for urinary tract infections, kidney disease, and to monitor for preeclampsia (indicated by proteinuria).

  4. Glucose Screening Tests:

    • Purpose: To screen for gestational diabetes.
    • Why Is It Ordered: To detect high blood sugar during pregnancy, which can increase the risk of complications for both the mother and the baby.

  5. Hepatitis B, Syphilis, and HIV Testing:

    • Purpose: To screen for these infections.
    • Why Is It Ordered: To prevent the transmission of these infections from mother to baby during pregnancy or delivery.

  6. Rubella and Varicella Immunity Status:

    • Purpose: To determine immunity to rubella (German measles) and varicella (chickenpox).
    • Why Is It Ordered: To ensure the mother has immunity, as these infections can cause serious birth defects or complications during pregnancy.

  7. Thyroid Function Tests:

    • Purpose: To assess thyroid hormone levels.
    • Why Is It Ordered: To monitor thyroid health, as changes in thyroid function can occur during pregnancy and affect both maternal and fetal well-being.

These tests are important components of prenatal care, helping to ensure the health and well-being of both the mother and the fetus throughout pregnancy. The specific tests ordered and their timing can vary based on the individual's health history, age, risk factors, and the course of the pregnancy.

Conditions or Diseases Requiring the Test:

The Obstetric Panel test is essential for routine prenatal care and for identifying potential risks, such as gestational diabetes, infections, anemia, Rh incompatibility, and more. Additionally, it helps determine the need for interventions to ensure a healthy pregnancy and safe delivery.

How Health Care Providers Use the Results:

  • Risk Assessment: The results guide healthcare providers in assessing the overall health of both the pregnant person and the fetus.
  • Interventions: If any abnormalities or risks are detected, appropriate interventions can be planned to manage or treat them.
  • Monitoring: Repeating the test at different stages helps monitor changes in health and make informed decisions for the well-being of both individuals.
  • Treatment Planning: Results guide treatment decisions, such as managing gestational diabetes or administering preventive measures for certain infections.

In conclusion, the Obstetric Panel test is a vital tool in prenatal care, offering a comprehensive assessment of health for pregnant individuals and their developing fetuses. By evaluating multiple parameters, healthcare providers can identify risks, make informed decisions, and ensure a safe and healthy pregnancy journey.

Most Common Questions About the Obstetric Panel test:

Clinical Utility and Interpretation

What is the primary purpose of the Obstetric Panel test?

The Obstetric Panel test is primarily designed to evaluate and monitor the health status of pregnant individuals and assess risks to both the mother and the fetus. It includes a series of blood tests that measure various components, such as blood cell counts, blood type, and specific antibodies.

How do the results from the Obstetric Panel test inform prenatal care?

The results can guide healthcare professionals in determining any potential risks or issues, such as anemia, gestational diabetes, or Rh incompatibility. Timely interventions can then be made to manage these risks and ensure the well-being of both the mother and the baby.

Clinical Applications and Diagnoses

Why is blood typing included in the Obstetric Panel test?

Blood typing, especially the Rh factor, is crucial in pregnancy. If an Rh-negative mother is carrying an Rh-positive fetus, there's a risk of Rh incompatibility, which could lead to hemolytic disease in the newborn. Early detection allows for preventive measures, such as administering Rh immunoglobulin.

Comparative Insights

How does the Obstetric Panel differ from other prenatal tests like amniocentesis or chorionic villus sampling (CVS)?

While the Obstetric Panel test focuses on the overall health and well-being of the pregnant individual, tests like amniocentesis and CVS are invasive procedures specifically designed to detect genetic or chromosomal abnormalities in the fetus.

Understanding Limitations and Challenges

If an abnormality is detected in the Obstetric Panel test, does it always indicate a serious issue?

Not necessarily. While abnormalities might suggest potential issues, they can sometimes result from temporary or benign conditions. It's crucial to consult with a healthcare professional for a comprehensive understanding of any abnormal findings.

Can the Obstetric Panel test replace all other prenatal tests?

No, the Obstetric Panel test is just one of many tests that can be conducted during pregnancy. While it offers valuable insights into the health of the pregnant individual and potential risks, other specialized tests might be needed based on individual circumstances and medical history.

Additional Questions and Insights

Does the Obstetric Panel test assess the risk of preeclampsia?

The test can provide indirect clues about the risk of preeclampsia by evaluating components like protein in the urine and platelet count. However, a comprehensive evaluation and regular monitoring are essential to diagnose and manage preeclampsia effectively.

Is the Obstetric Panel test recommended for all pregnant individuals?

Yes, most healthcare professionals recommend the Obstetric Panel test as a part of routine prenatal care for all pregnant individuals. It provides a comprehensive overview of the mother's health and highlights any potential concerns that might need further attention.
