• Potassium, RBC
• Potato (f35) IgE
• Potato (f35) IgG
• Pre-Albumin A protein made by the liver that reflects recent (days, not weeks) nutritional and protein status — useful for tracking short-term nutrition changes.
• Pregnenolone A hormone made from cholesterol that's the starting building block for all your other steroid hormones, including cortisol, DHEA, and sex hormones.
• Pristanic Acid
• Privet (t210) IgE
• Procalcitonin
• Procollagen Type I Intact N Terminal Propeptide
• Progesterone A hormone essential for the menstrual cycle and pregnancy. Used to confirm ovulation, evaluate fertility, and monitor early pregnancy.
• Prolactin A pituitary hormone best known for stimulating milk production; also checked to evaluate menstrual irregularities, fertility issues, or pituitary conditions in men and women.

• Prostate-Specific AntigenPSA A protein made by the prostate gland. Used to help screen for and monitor prostate cancer, though it can also rise with benign prostate conditions.
• Prostate-Specific Antigen (PSA), Free The unbound portion of prostate-specific antigen. Used alongside total PSA to help assess prostate cancer risk, especially when total PSA is borderline.
• Prostate-Specific Antigen (PSA), % Free The percentage of your PSA that's unbound to blood proteins. A lower percentage raises suspicion for prostate cancer, helping refine an elevated total PSA result.
• Prostatic Acid PhosphatasePAP An older prostate marker, largely replaced by PSA, occasionally still used in specific prostate cancer monitoring contexts.
• Protein
• Protein C Activity Measures the activity of Protein C, a natural anticoagulant. Low activity is linked to an increased risk of blood clots.
• Protein C Antigen Measures the actual amount of Protein C protein present, used together with the activity test to fully characterize a Protein C deficiency.
