Question 84

Blood for paternity testing requires a chain of custody form.

In cases of paternity testing, maintaining the integrity of the sample is crucial, which is why a chain of custody form is necessary. This documentation ensures that the sample has been collected, handled, and analyzed properly without tampering.

A) Blood for HIV testing

Blood specimens for HIV testing do not typically require a chain of custody form because they are usually analyzed for medical purposes rather than legal ones. The focus here is on patient care and confidentiality rather than on legal admissibility.

B) Sputum for tuberculosis testing

Sputum specimens for tuberculosis testing are primarily collected for diagnostic purposes and do not require a chain of custody form. The process surrounding these specimens is less about legal evidence and more about public health management.

C) Blood for paternity testing

Blood specimens collected for paternity testing necessitate a chain of custody form to ensure the sample's authenticity and integrity for potential legal proceedings. This form tracks the handling and transfer of the sample to prevent disputes about its origin or contamination.

D) Swab for chlamydia testing

Swab specimens for chlamydia testing are generally used for medical diagnostics and do not require a chain of custody form. The legal implications are minimal compared to those associated with paternity testing, where the results can have significant legal ramifications.

Conclusion

The requirement for a chain of custody form is specific to blood specimens collected for paternity testing due to the legal implications that may arise from the results. Other options, while important for medical diagnostics, do not possess the same legal necessity, which makes them inappropriate choices in this context. Thus, option C is the only correct answer.
