a housing comprising:

a cavity, wherein the first body, the fluid porous body, and the cleaning test soil are positioned within the cavity;

a first port; and

a second port, the first port and second port in fluid engagement with the cavity.

11. The device of claim 10 , further comprising a reservoir positioned within the cavity, the reservoir comprising a seal configured to retain growth media separate from the biological material.

12. The device of claim 1 , wherein the fluid porous body surrounds an outer surface of the first body.

13. A method for indicating a level of treatment in a treatment apparatus, the method comprising:

introducing a device into the treatment apparatus, the device comprising:

a first body, wherein the first body comprises at least one of a solid sheet, a perforated sheet, an amorphous support, a membrane, and a filter;

a biological material disposed on the first body, in the first body, adhered to the first body, or a combination thereof;

a fluid porous body connected to the first body via a fluid path, wherein the fluid porous body is positioned upstream from the first body in the fluid path; and

a cleaning test soil disposed in interstitial spaces of the fluid porous body to inhibit traversal of a fluid through the fluid porous body to the first body and the biological material via the fluid path such that the cleaning test soil is disposed within the fluid porous body;

subjecting the device to a cleaning process and at least one of a disinfection process and a sterilization process; and

measuring a quantity of active biological material in the first body following the cleaning process and the at least one of the disinfection process and the sterilization process.

14. The method of claim 13 , further comprising incubating the device with growth media.

15. The method of claim 14 , wherein measuring the quantity of active biological material in the first body comprises measuring an electromagnetic property of at least one of the growth media and the active biological material.

16. The method of claim 15 , wherein the electromagnetic property is at least one of absorption, transmittance, scattering, reflectance, and photoluminescence.

17. The method of claim 15 , wherein the electromagnetic property is measured at a wavelength in a range of 100 nm to 1000 nm.

18. The method of claim 13 , wherein the device is a first device and the method further comprises comprising:

introducing a second device to be treated into a treatment basin of the treatment apparatus; and

introducing the first device into a vessel.

19. The method of claim 18 , wherein the vessel is positioned separate from the treatment basin.

20. A method of preparing a device, the method comprising:

forming a first body, wherein the first body comprises at least one of a solid sheet, a perforated sheet, an amorphous support, a membrane, and a filter;

depositing a biological material, wherein the deposited biological material is disposed on the first body, in the first body, adhered to the first body, or a combination thereof; and

forming a fluid porous body comprising a cleaning test soil; and

connecting the fluid porous body to the first body via a fluid path, the cleaning test soil disposed in interstitial spaces of the fluid porous body to inhibit traversal of a fluid through the fluid porous body to the first body and the biological material via the fluid path such that the cleaning test soil is disposed within the fluid porous body.

21. The method of claim 20 , wherein the cleaning test soil is positioned separate from the biological material.

22. The method of claim 20 , wherein the cleaning test soil comprises at least one of a protein a derivative of a protein, a carbohydrate, a nucleic acid, a lipid, a salt, and an acid.

23. The method of claim 20 , wherein the cleaning test soil comprises at least one protein selected from the group consisting of a blood protein, collagen, keratin, casein, and mucin.
