Anemia Profile (Advanced) (Quest Diagnostics)

Same day lab order delivery

HSA/FSA reimbursable

Description

Anemia is a deficiency of red blood cells and/or hemoglobin. The most common type of anemia is iron deficiency anemia. The Anemia Profile measures the level of anemic-related blood chemistries.

A significant deviation from the normal range may require further evaluation by your physician.

Includes

Complete Blood Count / CBC (includes Differential and Platelets): WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, MCHC, RDW, Platelet Count, MPV and Differential (Absolute and Percent - Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils)
Ferritin, Serum
Folate (Folic Acid)
Iron, Serum w/ TIBC: Total Iron, Iron Binding Capacity, % Saturation (calculated)
Reticulocyte Count
Vitamin B12

Patient Instructions

Specimens should be collected in the morning from patients in a fasting state, since iron values decrease by 30% during the course of the day and there can be significant interference from lipemia. Some tests in this panel may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H or coenzyme R). Patient should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample. Folate assays of samples from patients receiving therapy with certain pharmaceuticals (eg, methotrexate or leucovorin), are contraindicated because of the cross-reactivity of folate binding protein with these compounds.

Estimated turnaround for results is 3 business days. If confirmation testing is required, the estimated time may be extended.

Autoimmune Profile (Quest Diagnostics)

Same day lab order delivery

HSA/FSA reimbursable

Description

Biotin (Vitamin B7) (Quest Diagnostics)

Same day lab order delivery

HSA/FSA reimbursable

Description

Biotin (Vitamin B7) - Biotin, vitamin B7, or vitamin H, is a water soluble vitamin. The vitamin plays a role in the transferring of carbon dioxide in the metabolism of fat, carbohydrate and protein by functioning as an enzyme cofactor. It is involved in multiple biochemical reactions including niacin metabolism, amino acid degradation, and the formation of purine, which is an integral part of nucleic acids. It interacts with histone by the action of biotinyl-transferase. Sometimes the vitamin is used in weight reduction programs. It may be prescribed as a supplement for diabetic patients due to its role in carbohydrate metabolism. Biotin is commonly found in vitamin B complex and many food sources, such as milk, yeast, egg yolk, cereal, and mushrooms. The reference daily intake [RDI of 101.9(c) (8) (IV)] for vitamin B7 is 300 micrograms. Deficiency in the vitamin may result in seborrheic dermatitis, alopecia, myalgia, hyperesthesia, and conjunctivitis. Disorders of biotin metabolism can be acquired or congenital. Biotinidase and holocarboxylase synthethase deficiency are the two better known forms of disorders. The lack of biotin-dependent pyruvate carboxylase, propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and acetyl-CoA carboxylase can lead to the life-threatening disorder of multiple carboxylase deficiency. Treatment involves a daily dose of approximately 10 mg biotin/day. Irreversible mental or neurological abnormalities may result from delayed clinical intervention.

Significant deviations from the normal range may require further evaluation by your physician.

Biotin (Vitamin B7)
