Workup

Approach Considerations

When healing or bleeding characteristics are concerns, consider performing screening blood tests, including tests of following:

  • CBC count with platelets
  • Prothrombin time (PT)
  • Activated partial thromboplastin time (aPTT)

Further testing (eg, chemical profile) is occasionally performed as the patient's medical condition dictates.

In female patients, extensive workup is indicated to rule out potentially treatable causes of the hair loss. Include tests of the following:

  • CBC count
  • Total iron and ferritin
  • Thyroid function tests and thyroid-stimulating hormone
  • Total and free testosterone
  • Dehydroepiandrosterone (DHEA) sulfate, in cases of irregular menses

Further testing (eg, ECG) is occasionally performed as the patient's medical condition dictates. It also may be prudent to screen for antibodies to HIV hepatitis B and C.

Classification

Staging alopecia into both pattern and degree of severity can be accomplished through the Hamilton classification. Patients with Hamilton patterns I and II have very early limited alopecia requiring minimal treatment if accepted as candidates. Conversely, patients with patterns VI and VII may no longer be candidates for the surgery since their alopecia is so extensive. The very best candidates fall into patterns IV to V, which produce the best, most natural results. See the image below.
