Toxocara Antibody (IgG), Serum
*Build Your Own Panel Eligible [?]
|
$402
|
|
|
Description:
The ELISA procedure utilizes the excretory-secretory(es) antigen of T. canis larvae to minimize cross-reactivity with antigens of Ascaris spp. and of other parasites. Results must be interpreted with caution as broad variations in antibody response occur and levels may remain elevated for years after infection. Generally, antibody levels are highest in visceral larva migrans (VLM). A negative result usually rules out infection with Toxocara spp.

Description:
Toxoplasma gondii, an obligate intracellular parasite, is an important opportunistic pathogen of immunosuppressed patients. In AIDS patients and transplant patients, this infection may result in a life-threatening encephalitis. T. gondii can also cause a fatal infection of the fetus if an infection is acquired during pregnancy. Fetal death or major abnormalities such as blindness and mental retardation may occur when infection is acquired during the first trimester. PCR methods may be useful in identifying T. gondii in CSF of immunosuppressed patients or in the amniotic fluid of mothers thought to be recently infected.

Description:
Trichomoniasis (or trich) is a very common sexually transmitted disease (STD) that is caused by infection with a protozoan parasite called Trichomonas vaginalis. Although symptoms of the disease vary, most women and men who have the parasite cannot tell they are infected.
Trichomoniasis is considered the most common curable STD. In the United States, an estimated 3.7 million people have the infection, but only about 30% develop any symptoms of trichomoniasis. Infection is more common in women than in men, and older women are more likely than younger women to have been infected.
Males, please order the Male version of this test: Trichomonas vaginalis RNA, Qualitative, TMA (Males)
Significant deviations from the normal range may require further evaluation by your physician.

Trichomonas vaginalis RNA, Qualitative, TMA, Pap Vial
*Build Your Own Panel Eligible [?]

|
Description:
Trichomonas vaginalis RNA, Qualitative Transcription- Mediated Amplification, Pap Vial test is a nucleic acid amplification test that uses transcription-mediated amplification for detection of T. vaginalis RNA, using a ThinPrep® or SurePath™ Pap sample as the specimen. It is used in the screening and diagnosis of trichomoniasis. When the clinical performance of this assay was evaluated, sensitivity was 100% in PreservCyt Solution liquid Pap specimens, while specificity was 98.6% [1,2].Trichomoniasis is one of the most common sexually transmitted infections (STIs) in the United States, with an estimated 1.1 million new cases each year [3]. It is curable. About 70% of people infected with T. vaginalis are asymptomatic, though symptoms may show up after the infection has been present for some time. In women, symptoms include vaginal and/or urethral discharge, painful urination, and genital burning and discomfort [4].In women, untreated T. vaginalis infection can lead to infertility, pelvic inflammatory disease, and cervical neoplasia. T. vaginalis infection is associated with a 2- to 3-fold increased risk for HIV infection in women, as well as increased risk of preterm labor [1].T. vaginalis testing is recommended for women with vaginal discharge or cervicitis [4]. Because of the high rate of reinfection in individuals treated for T. vaginalis, repeat testing 3 months after treatment is recommended. Additionally, screening is recommended for HIV-infected women at the first HIV-related visit, with follow-up T. vaginalis testing annually. For pregnant women with HIV infection, T. vaginalis screening is recommended at the first prenatal visit [1].A "detected" result is consistent with T. vaginalis infection. False-positive results could be obtained from sampling less than 2 weeks after cessation of therapy, since TMA-based tests can detect nucleic acids from dead organisms. A "not detected" result is consistent with the absence of T. vaginalis infection. False-negative results could be obtained due to an organism concentration below the assay detection limit [1].References1. Workowski, KA et al.

Description:
This allergen-specific IgE antibody test quantifies an individual’s IgE response to Trichophyton mentagrophytes var interdigital. It is an in vitro quantitative assay that is intended to be used in conjunction with other clinical information to aid in the diagnosis of allergic diseases [1]. While allergen-specific serum IgE testing is considered comparable to skin testing in many instances, both the American Academy of Allergy, Asthma, and Immunology and the American College of Allergy, Asthma, and Immunology recognize that allergen-specific serum IgE testing may be preferred in some clinical situations. These include 1) the presence of widespread skin disease, 2) the recent use of antihistamines or other medications that can affect the results of allergy skin tests, 3) uncooperative patients, and 4) medical history suggesting that allergen skin testing would pose a significant risk for a serious allergic reaction [1]. A definitive clinical diagnosis of allergy should not be based on the results of any single diagnostic method, but should be made by a trained healthcare provider after all clinical and laboratory findings have been evaluated. More specific information about this allergen can be found at http://www.phadia.com/en/Products/Allergy-testing-products/ImmunoCAP-Allergen-Information/Molds-and-other-Microorganisms/Allergens/Trichophyton-ment-var-interdigitale-/ Reference 1.

TSH Antibody
*Build Your Own Panel Eligible [?]

Description:
This test may help identify thyroid stimulating hormone (TSH) autoantibodies. When the serum TSH level is discordant with clinical manifestations or other test results (eg, markedly elevated TSH with normal free triiodothyronine and free thyroxine levels), this test may be used to determine if TSH autoantibodies are the cause of discordance.TSH autoantibodies can bind TSH to form a macromolecule (macro-TSH) that has low biological activity but interferes with TSH immunoassays [1]. Interference by macro-TSH may be screened by polyethylene glycol precipitation and gel filtration chromatography [1].Anomalous TSH levels may also be caused by a range of interfering substances, such as biotin, heterophilic antibodies, and antibodies to streptavidin and ruthenium [1].Other conditions that may result in elevated TSH levels with normal free triiodothyronine and free thyroxine levels include subclinical hypothyroidism, poor adherence to (or malabsorption of) thyroxine therapy, certain drugs (eg, amiodarone), nonthyroidal illness recovery phase, and TSH resistance [2].The results of this test should be interpreted in the context of pertinent clinical and family history and physical examination findings.References1.

Description:
TSH levels are lower during pregnancy, especially during the 1st trimester. Based on recent clinical studies which have shown that even mildly elevated TSH during pregnancy is associated with adverse pregnancy outcomes, the American Thyroid Association has released clinical guidelines which recommend the use of assay-specific and trimester-specific reference intervals.

|
|
Description:
Precision in the estimation of TSH is crucial to the follow-up of subjects with thyroid disorders. The preincubation of samples to remove HAMA immunoglobulins provides a way to ensure that an otherwise unsuspected rise or drop in TSH concentration will not be interpreted as either a false positive or false negative.

TSH with Reflex to Free T4

Description:
This test may be useful in assessing thyroid dysfunction when pituitary disease is not suspected. In patients with clinical suspicion of hyperthyroidism or hypothyroidism, testing thyroid stimulating hormone (TSH) is the initial step [1]. An abnormal TSH result will reflex to a free thyroxine (T4) test to aid in diagnosis and guide further testing if needed.TSH stimulates the thyroid gland to synthesize and secrete triiodothyronine (T3) and T4. TSH production is reduced in response to high T3/T4 levels and increased in response to low T3/T4 levels. When pituitary disease is not suspected, TSH serves as a sensitive marker for screening for thyroid dysfunction [1,2]. A normal TSH result excludes most cases of primary overt thyroid disease. When the TSH level is elevated, measurement of free T4 level may help diagnose subclinical or overt hypothyroidism. Thyroid peroxidase antibody testing may be needed to aid in the diagnosis of Hashimoto thyroiditis. When the TSH level is decreased, measurement of free T4 and free T3 may help identify hyperthyroidism or T3 thyrotoxicosis. In patients with thyrotoxicosis, TSH receptor antibodies testing helps confirm Graves disease [1-3].Note: Interference due to heterophile antibodies has been known to occur [1].The results of this test should be interpreted in the context of pertinent clinical and family history and physical examination findings.References1.
