FAQs

Why is the midstream clean-catch technique used for urine collection?
It helps avoid contamination by flushing away bacteria normally present near the opening, so the sample shows only what is inside the bladder.

What happens if a blood specimen is not transported to the lab on time?
Delays can cause cells to break down or bacteria to multiply, leading to wrong test results and possibly incorrect treatment.

Do I need sterile containers for every specimen?
Yes, most specimens require sterile containers to prevent outside germs from mixing in. Always check the lab guidelines for the exact container type.
