Table 2. Pregnancy test characteristics.

Test Type	Location	Typical Sensitivity (IU/L)*
Qualitative
• Urine	Home/Point-of-care	20–25
• Serum	Lab	~10
Quantitative
• Serum	Lab	2 (cutoff 5 IU/L)

*Reviewing the specific package inserts of the assay used is strongly recommended because testing sensitivity may vary between tests in addition to the way sensitivity is described. These values are based on: Snyder 2005 [9], Cervinski MA, Lockwood CM, Ferguson AM, et al.
