Anemia Profile (Advanced)  (Quest Diagnostics)

Same day lab order delivery

HSA/FSA reimbursable
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.
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
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
Uncovering autoimmune disease through specific autoimmune blood tests can lead to treatments designed to prevent or slow your immune system from attacking itself. Autoimmune blood tests and other screening tests of the immune system can help limit illnesses and offer more favorable outcomes.

Significant deviations from the normal range may require further evaluation by your physician.
ANA Screen IFA w/ Ref to Titer and Pattern
If ANA Screen, IFA is positive, ANA Titer and Pattern will be performed.
Anti-dsDNA (Double-Stranded) Antibiodies, EIA
Complement Component C3c 


Estimated turnaround for results is 5 business days.

No fasting required.

Estimated turnaround for results is 5 business days. If confirmation testing is required, the estimated time may be extended.

Dihydrotestosterone, (DHT) LC/MS/MS  (Quest Diagnostics)

Same day lab order delivery

HSA/FSA reimbursable
The Dihydrotestosterone (DHT) test measures the level of DHT in the blood. DHT is naturally occurring androgen and aids in the development of the prostate and male gentalia.
DHT is a potent androgen derived from testosterone via 5-alpha-reductase activity. 5-alpha-reductase deficiency results in incompletely virilized males (phenotypic females). This diagnosis is supported by an elevated ratio of testosterone to DHT.

Alternative Names(s): DHT

A significant deviation from the normal range may require further evaluation by your phyisician.
Dihydrotestosterone, LC/MS/MS

Estimated turnaround for results is 7 business days

No fasting required.

Estimated turnaround for results is 7 business days. If confirmation testing is required, the estimated time may be extended.

Biotin (Vitamin B7)  (Quest Diagnostics)

Same day lab order delivery

HSA/FSA reimbursable
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.

FAQ

  1. Why would I need a blood test for hair loss?

    These tests are performed to help identify potential causes of hair loss, such as:

    • Hormonal imbalances
    • Nutritional deficiencies
    • Autoimmune disorders
    • Other medical conditions

    Blood work for hair loss can help you identify the underlying causes of your hair loss and formulate a treatment plan that can help manage and/or reverse the issue.

  2. What are hair loss blood tests?

    Hair loss blood tests are diagnostic tests that involve analyzing a blood sample to identify underlying causes of hair loss. These tests measure specific markers or substances in the blood that contribute to hair loss.

    Our Hair Loss Trust Me Medium tests for the following valuable biomarkers:

    • Iron
    • Ferritin
    • Vitamin B12
    • Dihydrotestosterone (DHT)
    • Testosterone, free & total
    • Thyroid profile
    • Vitamin D
    • CBC
    • ANA
    • C-RP

    These markers provide a deeper insight into hair loss through analysis of hormones, nutrient levels, inflammation and autoimmune conditions that affect your hair’s health and volume.

  3. What are the most common types of hair loss?

    The most common types of hair loss are:

    • Androgenetic Alopecia (Male/Female Pattern Baldness)
    • Telogen Effluvium
    • Alopecia Areata
    • Traction Alopecia
    • Trichotillomania
    • Alopecia Universalis/Totalis

    Keep in mind that this is not an exhaustive list, and there are other less common forms of hair loss as well. Tests for hair loss can help you identify the type of hair loss you’re experiencing, and get the right treatment for you.

  4. Can hair loss blood work determine the exact cause of my hair loss?

    Yes. These tests can provide valuable information about potential underlying causes of hair loss. Testing for hair loss can also involve a biopsy of the scalp or a physical exam in addition to blood tests in order to determine the exact diagnosis for that human.

  5. How long does it take to get the results of hair loss blood tests?

    Your results will be delivered by email in 3-7 business days after the collection of your sample.

  6. Can a blood test for alopecia predict if my hair will regrow?

    Alopecia blood tests can provide insights into potential underlying causes of hair loss, but they cannot definitively predict if or how much hair will regrow. The regrowth of hair depends on various factors, including:

    • Underlying cause(s)
    • Treatment options
    • Individual response to treatment
    • Overall health
  7. Do I need to visit a doctor?
