PEP A2Glob, also known as Pepsinogen A2 Globulin, is a specific biomarker of considerable interest in the field of gastroenterology and digestive health. Pepsinogen, an inactive precursor of the enzyme pepsin, plays a critical role in protein digestion within the stomach. It is secreted by the gastric chief cells and is converted to active pepsin in the acidic environment of the stomach. The A2 globulin variant of pepsinogen, or PEP A2Glob, is one of the multiple isoforms of pepsinogen. Elevated levels of PEP A2Glob can be indicative of certain gastric conditions.

Peptostreptococcus is a type of bacteria that is part of the normal flora in the human gut but can become noteworthy under certain conditions. The Gut Zoomer panel is a comprehensive test designed to provide a detailed look at the microbial environment within the gastrointestinal tract, offering insights into the balance of beneficial and potentially harmful bacteria. Peptostreptococcus, in this context, is highlighted because its levels can have implications for an individual's health. When in balance, Peptostreptococcus plays a role in the normal processes of the gut, such as helping in the breakdown of proteins and other substances. However, if its levels become too high, it may indicate an imbalance in the gut microbiota, which can be associated with various health issues, including inflammatory conditions and infections. The presence and concentration of Peptostreptococcus, as identified by the Gut Zoomer panel, can therefore provide valuable information for diagnosing gut health issues and guiding treatment decisions. It's essential to interpret these results within the broader context of an individual's health, symptoms, and other test outcomes, ideally under the guidance of healthcare professionals familiar with gut health and the microbiome.

The percentage of A+B motility in semen analysis is a crucial indicator of sperm's ability to effectively move and play a role in natural conception. Higher percentages are generally associated with better fertility outcomes.

Perchlorate (PERC) is a naturally occurring and man-made anion and is a powerful oxidizing agent. It is mainly used for propellants in rocket fuel as well as control static electricity in food packaging. Perchlorate may be accumulated into vegetables through water cycle and other parts in the environment. Perchlorate contamination in food and water has been found to be harmful for human health. Perchlorate is classified as a possible carcinogen. It may disrupt the thyroid’s ability to produce hormones. It has also been linked with lung toxicity and aplastic anemia.

The chemical Perchlorate (PERC) is used in the production of rocket fuel, missiles, fireworks, flares, explosives, fertilizers, and bleach. Studies show that perchlorate is often found in water supplies. Many food sources are also contaminated with percholate. Percholate can disrupt the thyroid’s ability to produce hormones. The EPA has also labeled perchlorate a likely human carcinogen.

Peruoropentanoate (PFPeA) is a short chain peruoroalkyl acid and used to make various products resistant to oil, stains, grease, and water. PFPeA is ubiquitous in the environment and is spread through water, food, and vehicles. Extensive public health data is not available regarding the health effects of PFPeA, however pre-clinical studies highlight potential concerns regarding cancer, endocrine disruption, accelerated puberty, liver dysfunction, immune system damage, and thyroid changes.

Atypical perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) occur in most patients with ulcerative colitis but only in a minority of those with Crohn's disease.

This ratio is helpful when both E2 and Pg are within range, yet the patient continues to have symptoms. It is not expected to be normal or used clinically when either E2 and/or Pg are outside of their expected ranges or if the patient does not have clinical symptoms.

Based on the optimal luteal levels of urinary Pgdiol (about 1300-2000 µg/g creatinine) an optimal working range for the ratio of this progesterone metabolite to estradiol was established based on the median level of urinary estradiol (1.37 µg/g creatinine). Thus the optimal working ratio of urinary Pgdiol to estradiol in the premenopausal woman during the peak luteal phase should be in the neighborhood of about 1000 to 1500.

Fecal pH is largely dependent on the fermentation of fiber by the beneficial flora of the gut.

Normal semen pH is in the range of 7.2 to 8 and it tends to increase with time after ejaculation. Changes are usually due to inflammation of the prostate or seminal vesicles.
