The prealbumin screen is a blood test that may be used to see if you are getting enough nutrition in your diet. This may be because you have a chronic condition. Or it may be because you have an infection or inflammation, or you suffered a trauma. 

Prealbumin is a protein that is made mainly by your liver. Your body uses it to make other proteins. Prealbumin also carries thyroid hormones in the blood

Evaluate protein malnutrition, total parenteral nutrition, and liver dysfunction. Values are decreased in inflammatory processes, malignancy, protein malnutrition, and protein wasting diseases of the gut or kidney. Values are increased in Hodgkin's disease.

What is Pre-Beta-1 HDL?

Pre-Beta-1 HDL, often referred to as Pre-b-1 HDL, is a distinct form of High-Density Lipoprotein (HDL), commonly known as "good cholesterol." This specific type of HDL is unique because it is the smallest and most compact form, serving as the starting point in the development of HDL particles. Pre-b-1 HDL plays a vital role in the reverse cholesterol transport process, where it collects excess cholesterol from your body's tissues and transports it back to the liver for removal. This process is crucial for maintaining the health of your heart and blood vessels. Essentially, Pre-b-1 HDL functions like a diligent cleaner, continually picking up and eliminating unwanted cholesterol from your body. Understanding the importance of Pre-b-1 HDL can help in managing cholesterol levels and promoting cardiovascular health.

Precoproporphyrin I is an atypical porphyrin formed when the heme pathway is under stress or when porphyrin metabolism becomes disrupted. It is not normally produced in significant amounts and can rise in response to metabolic strain or certain environmental exposures.

Precoproporphyrin II is an atypical porphyrin formed outside the usual heme synthesis pathway. It is measured to help identify stress in porphyrin metabolism, metabolic imbalance, or environmental exposures that can interfere with heme production.

Precoproporphyrin III is a non-standard porphyrin metabolite that may appear when the heme synthesis pathway is disrupted. Its levels can reflect metabolic stress, oxidative burden, or environmental exposures that interfere with porphyrin metabolism.

The Precoproporphyrins/Uroporphyrins ratio compares the amount of atypical porphyrins to early-stage classical porphyrins. Changes in this ratio may indicate metabolic stress, oxidative imbalance, or environmental exposures that disrupt normal heme metabolism.

Progesterone itself is not readily found in the urine. Instead, this test measures pregnanediol (a progesterone metabolite). Pregnanediol is well-established in research literature as a reliable marker for progesterone levels.

Progesterone rapidly metabolizes by the time it reaches the urine, and its direct metabolite, pregnanediol, is a reflection of circulating progesterone concentrations.

Pregnanediol, a key marker in male health, is prominently featured in the ZRT Laboratory Urinary Neurotransmitters panel. Pregnanediol is a metabolite of progesterone, a hormone often associated with female reproductive health but equally important in males. In men, progesterone, and consequently pregnanediol, play roles in regulating the central nervous system, influencing mood, and contributing to the synthesis of other crucial steroids like testosterone.

Abnormal levels of pregnanediol in men can indicate various health concerns, including adrenal issues, hormonal imbalances, and even potential impacts on prostate health.

Progesterone is metabolized into numerous downstream compounds, but most immediately into pregnanediol and pregnanetriol. Urine levels of these metabolites tend to correlate with levels of serum progesterone, thus may be used to assess status of the hormone.

Pregnenolone is a chemical substance that is a precursor to all steroid hormones.

Pregnenolone, measured in nanograms per milliliter (ng/mL), is a crucial neurosteroid in males, acting as a precursor to various other steroids including progesterone, mineralocorticoids, glucocorticoids, androgens, and estrogens. It is synthesized directly from cholesterol and serves as the foundational substrate in the steroidogenesis pathway, leading to the production of these hormones.

This steroid plays a vital role in brain function, as it is involved in neurogenesis, synaptic functioning, and neural plasticity, and it also influences mood and memory.
