What the laboratory says this test is for

This panel is designed to evaluate a patient for the presence of potentially reversible (i.e., secondary) causes of dementia such as Vitamin B12 deficiency, hypothyroidism, hypoparathyroidism, anemia, hypoxia or hypercapnia, hepatic and renal encephalopathies, diabetes and dehydration.The panel includes a Complete Blood Count, TSH, Vitamin B12, Folate and a Comprehensive Metabolic Panel. It is modeled after the recommendations of the American Academy of Neurology (AAN), a National Institutes of Health Consensus Panel, the European Federation of Neurological Societies (EFNS), and others [1-4].References1.

What the laboratory says this test is for

This panel includes tests used for routine prenatal care during early pregnancy, which have been recommended for all women during early pregnancy by the American College of Obstetricians and Gynecologists (ACOG) [1]. An alternative panel, the Obstetric Panel with Fourth Generation HIV (test code 93802), is available and may be ordered to simultaneously screen for HIV infection.Additional tests typically done in early pregnancy (but not included in this panel) include urinalysis, tests for sexually transmitted infections and tuberculosis, and blood glucose testing for women at high risk for gestational diabetes.The CBC with differential evaluates the levels and types of red blood cells, white blood cells, and platelets in the patient's blood. This information can help identify conditions such as anemia, low platelet count, and other blood cell disorders [1].The blood type, including ABO and Rh status, as well as the antibody screen, will provide information about a women's current and/or future risk for hemolytic disease of the fetus and newborn. These tests may also be useful to define any special transfusion requirements [1].Syphilis, when transmitted from mother to fetus, may cause birth defects and neonatal death [2]. Syphilis testing is performed using a combination of assays. The RPR is performed initially. If the result is reactive, a titer and a confirmatory test (fluorescent treponemal antibody absorption assay; FTA-ABS) will be performed at additional cost.Hepatitis B, a disease that affects the liver, can be passed from mother to fetus [1]. Hepatitis B screening is performed with the hepatitis B surface antigen test. If positive, additional confirmatory testing based on the test manufacturer's FDA-approved recommendations will be performed at additional cost.Rubella, or German measles, can cause birth defects if transmitted from mother to baby during pregnancy. Testing of the mother's immune status against rubella will indicate if the mother and baby are protected from infection by the virus during this time. Vaccination for rubella during pregnancy is not recommended [1].Note: Test results should be interpreted in the context of pertinent clinical and family history and physical examination findings.References1.

What the laboratory says this test is for

This panel includes tests used for routine prenatal care during early pregnancy, including HIV-1/2 Antigen and Antibodies, Fourth Generation, with Reflexes and Hepatitis C Antibody with Reflex to HCV, RNA, Quantitative, Real-Time PCR, which have been recommended for all women during early pregnancy by the American College of Obstetricians and Gynecologists (ACOG) [1, 3]. Alternative Panels are: Obstetric Panel (test code 20210), Obstetric Panel with Fourth Generation HIV (test code 93802).Additional tests typically done in early pregnancy (but not included in this panel) include urinalysis, tests for sexually transmitted infections and tuberculosis, and blood glucose testing for women at high risk for gestational diabetes.The CBC with differential evaluates the levels and types of red blood cells, white blood cells, and platelets in the patient's blood.

Testing of the mother's immune status against rubella will indicate if the mother and baby are protected from infection by the virus during this time. Vaccination for rubella during pregnancy is not recommended [1].Hepatitis C (HCV) screening is recommended by the American College of Obstetricians and Gynecologists for all pregnant individuals during each pregnancy. HCV screening during the first prenatal blood assessment obtained in every pregnancy is recommended to identify pregnant individuals with HCV infection and infants who should receive testing at a pediatric visit [3]. For the pregnant person, diagnosing HCV infection in early pregnancy gives providers the opportunity to reduce the risk of HCV vertical transmission with preferential performance of amniocentesis over chorionic villus sampling when needed, and avoidance of prolonged rupture of membranes, episiotomy, and fetal scalp monitoring when possible. Furthermore, children born to mothers with diagnosed HCV infection can be tested as early as 2 months of age and monitored for treatment needs to prevent progression to cirrhosis. Finally, persons diagnosed with HCV during pregnancy can receive treatment for hepatitis C, postnatally, to prevent progression to cirrhosis, liver failure, and death as well as reduce the risk of HCV transmission.

Post COVID-19 Expanded Panel

Specimen
See individual tests
Fasting
Not stated as required

What the laboratory says this test is for

About 10-30% of patients continue with lingering symptoms four or more weeks after COVID-19 infection, including those who had mild, or no symptoms termed as post-COVID conditions. The Centers for Disease Control (CDC) provided Interim Guidance for Assessment and Testing for Evaluating and Caring for Patients with Post-COVID Conditions. The CDC recommends laboratory testing be guided by the patient history, physical examination, and clinical findings. A basic panel of laboratory tests might be considered for patients with ongoing symptoms to assess for conditions that may respond to treatment, until more information and evidence is available for specific laboratory testing for post-COVID conditions. This panel is to be considered for basic testing if no previous testing was performed.

What the laboratory says this test is for

This panel is useful in assessing the risk of any underlying medical conditions prior, during, and after initiation of therapy for Hepatitis C. This baseline profile does not include Hepatitis A or Hepatitis B testing, under the assumption this testing has already been performed. If these tests are desired, consider using 91704 (Hepatitis C-Infected Patient, Baseline Panel 1) or ordering separately. The relevant laboratory monitoring has been defined in the most recent AASLD guidelines.
