Your results are reviewed with the health information you share.

Understand your testing options
Which blood tests may help investigate hair loss?
Iron studies, ferritin, thyroid tests and a CBC can help investigate selected contributors to hair shedding. The useful tests depend on your symptoms, scalp examination and history. This package brings those specific measurements together for $110.
Iron and ferritin
Check stored and circulating iron alongside a blood count. Your clinician can connect the results with your eating patterns, menstrual history and previous iron levels.
Thyroid measurements
TSH, free T3 and free T4 add thyroid information to the assessment when your clinician has recommended these tests.
Your hair-loss timeline
Note when shedding began and any recent illness, pregnancy, major eating changes or new medicines. These details help make the lab results useful.
A blood test is one part of a hair-loss assessment. Scalp findings and the pattern of loss help your clinician choose next steps. Results can guide a nutrition discussion when a deficiency is identified.
Choose the package that matches your requested tests. The $90 iron and ferritin package focuses on iron studies and a CBC. This $110 package adds the listed thyroid tests. Quest collection is included in both prices.

Your questions,
answered.
Which blood tests are included for hair shedding?
This package combines iron studies and ferritin with TSH, free T3, free T4 and a CBC with differential. The complete biomarker list is shown above.
When might these tests be appropriate?
Persistent shedding, a history of low iron, heavy menstrual bleeding or a clinician’s concern about thyroid function may prompt a discussion about targeted bloodwork. The pattern and timing of hair changes matter, so bring a timeline and previous results.
Will these tests diagnose the cause of hair loss?
Bloodwork can help investigate selected causes when your clinician thinks it is useful. A scalp examination and history may be more important for other types of hair loss. This package cannot diagnose every cause or predict how much hair will grow back.
Should I choose this or the iron package?
This $110 package includes iron studies, a CBC and the listed thyroid tests. The iron and ferritin package is $90 and focuses on iron studies and a CBC. Choose the combination that fits your clinician’s requested tests.
What should I mention before the blood draw?
Tell your clinician about recent illness, surgery, pregnancy, weight or eating changes, medicines and supplements. In particular, mention hair-and-nail supplements containing biotin and follow the laboratory’s preparation instructions.
