Leases [Abstract]
Leases	LeasesLessor Activity - Leases where Hologic is the LessorCertain assets, primarily diagnostics instruments, are leased to customers under contractual arrangements that typically include an operating lease and performance obligations for disposables, assays, tests and other consumables. These contractual arrangements are subject to termination provisions which are evaluated in determining the lease term for lease accounting purposes. Contract terms vary by customer and may include options to terminate the contract or options to extend the contract. Where instruments are provided under operating lease arrangements, some portion or the entire lease revenue may be variable and subject to subsequent non-lease component (e.g., reagent) sales. Sales-type leases are immaterial. The allocation of revenue between the lease and non-lease components is based on stand-alone selling prices. Lease revenue represented less than 5% of the Company's consolidated revenue for all periods presented.
