Thyroglobulin Level

The thyroglobulin test is primarily used as a tumor marker to evaluate the effectiveness of treatment for thyroid cancer and to monitor for recurrence. Not every thyroid cancer will produce thyroglobulin, but the most common types, the well-differentiated papillary and follicular thyroid cancers, frequently do, resulting in increased levels of thyroglobulin in the blood.

Reference Values: Up to 55 ng/ml

Method: CLIA

Loinc: 3013-0

TIBC-Total Iron Bind. Capacity

Total iron binding capacity (TIBC) is a blood test that measures iron levels in the blood. The test helps measure the ability of a protein called transferrin to carry iron in the blood.

Reference Values:

3-12 Months: 290-436 μg/dl
1-3 Years Old: 274-475 μg/dl
4-10 Years Old: 262-497 μg/dl
11-16 Years Old: 290-441 μg/dl
Adults: 250-450 μg/dl

Method: Colorimetric/Enzymατιψ

Loinc: 2500-7

Total Protein

A total serum protein test measures the total amount of protein in the blood. It also measures the amounts of two major groups of proteins in the blood: albumin and globulin.

Specimen: Serum

Reference Values: 6.3-8.2 g/dl

Method: Biuret Reaction

Loinc: 2885-2

Total Protein (Urine)

The 24-hour urine protein test checks the function of the kidneys and detects disease.

Specimen: Urine

Reference Values:

24 Hours Urine: <150 mg/24hours

Random Urine: <30 mg/dl

Method:Photometric

Loinc: 2889-4

Total T3

Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate.

Specimen: Serum

Reference Values:

Method:

Loinc: 14930-2

Total T4 (Thyroxine)

Thyroxine (T4) is synthesized in the thyroid gland. T4 is metabolized to triiodothyronine (T3) peripherally by deiodination. T4 is considered a reservoir or prohormone for T3, the biologically most active thyroid hormone.

Specimen: Serum

Reference Values: 60-161 nmol/L

Method: CLIA

Loinc: 3026-2

Toxoplasma Avidity Test

The avidity determination is a diagnostic method which is used to differentiate a recent (acute) and a more distant (past) infection with Toxoplasma gondii in patient sera. Avidity is the binding force of the antibody (serum specimen) with the corresponding antigen.

Specimen: Serum

Reference Values:

>30%: High (Past Infection)
20-30%: Equivocal
<20% Low (Acute Infection)

Method:

Loinc: 56990-5

Toxoplasma IgG

A single-celled parasite called Toxoplasma gondii causes a disease known as toxoplasmosis. However, pregnant women and individuals who have compromised immune systems should be cautious , for them, a Toxoplasma infection could cause serious health problems Toxoplasma IgG = Past Infection

Specimen: Serum

Reference Values:

Non Reactive: <1.0 IU/ml
Equivocal: 1.0-2.99 IU/ml
Reactive: >3.0 IU/ml

Method: CLIA

Loinc: 21569-9

Toxoplasma IgM

A single-celled parasite called Toxoplasma gondii causes a disease known as toxoplasmosis. However, pregnant women and individuals who have compromised immune systems should be cautious , for them, a Toxoplasma infection could cause serious health problems Toxoplasma IgM = Acute Infection

Specimen: Serum

Reference Values:

Non Reactive: <0.8
Equivocal: 0.8-1.0
Reactive: >1.0

Method: CLIA

Loinc: 21571-5

TPHA Antibodies

The Treponema pallidum particle agglutination assay (also called TPPA test) is an indirect agglutination assay used for detection and titration of antibodies against the causative agent of syphilis, Treponema pallidum subspecies pallidum .

Specimen: Serum

Reference Values:

Negative: <0.8
Equivocal: 0.8-1.2
Positive: >1.2

Method:

Loinc: 26009-1

Triglycerides

Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn’t need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals. If you regularly eat more calories than you burn, particularly “easy” calories like carbohydrates and fats, you may have high triglycerides

Specimen: Serum

Reference Values:

Normal: <150 mg/dl
Borderline High: 150-199 mg/dl
High: >200 mg/dl

Method: Enzymatic

Loinc: 2571-8

Trypsin Activity, Stools

Trypsin is always present in high amounts is stools of normal children. In adults the activity is much less because of proteolytic bacteriae in adult gastrointestinal tract. Low trypsin activity in children is associated with malabsorbtion disease.

Specimen: Stool

Reference Values:

Method:

Loinc: 26960-5

Tryptase

Tryptase is an enzyme that is released, along with histamine and other chemicals, from mast cells when they are activated as part of a normal immune response as well as in allergic (hypersensitivity) responses. This test measures the amount of tryptase in the blood.

Specimen: Serum

Reference Values: <11.0 ug/L

Method: FEIA

Loinc: 21582-2

TSH (Thyroid Stimul. Hormone)

A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.

Specimen: Serum

Method: CLIA
