Proteinuria is a condition in which an abnormal amount of protein is present in the urine, often indicating underlying kidney dysfunction or systemic health issues.

Causes of Proteinuria

The causes of proteinuria can vary widely, ranging from temporary conditions to chronic diseases. Common causes include:

Kidney disorders such as Chronic Kidney Disease and Glomerulonephritis

Systemic conditions like Diabetes Mellitus and Hypertension

Infections, fever, or intense physical activity (temporary proteinuria)

Autoimmune diseases such as Lupus

Dehydration or prolonged stress

Signs and Symptoms

In many cases, proteinuria may not cause noticeable symptoms in its early stages. However, as it progresses, individuals may experience:

Foamy or frothy urine

Swelling (edema), especially in the hands, feet, abdomen, or face

Fatigue and weakness

Shortness of breath (in severe cases)

Unexplained weight gain due to fluid retention

Bay Biosciences, therefore, specializes in providing human tissue samples, including fresh frozen tissue samples and formalin fixed paraffin embedded (FFPE) tissue samples. Specifically, we collect and provide human tissue samples from most diseases, including some of the rare conditions. Moreover, we maintain our own repository with thousands of fresh frozen tissue samples and millions of FFPE tissue samples.

Tuberculosis (TB) is a contagious lung disease that remains a major global health concern despite past declines due to antibiotics. Today, rising case numbers and drug-resistant strains have renewed urgency for innovation, making Tuberculosis Samples for Research essential for advancing diagnostics, drug development, and treatment strategies. These samples support deeper scientific understanding and help address the evolving challenges of TB worldwide.

At Bay Biosciences, we provide high-quality human stool samples for microbiome, gastrointestinal, and infectious disease research. All specimens are ethically collected and processed under strict quality controls to ensure microbial integrity and consistency. Our research-ready stool samples support metagenomics, biomarker discovery, and diagnostic development. With a strong focus on accuracy and scientific excellence, Bay Biosciences delivers dependable specimens that help drive meaningful breakthroughs.

Trouble breathing can arise from a wide range of conditions, from common colds, flu, or anxiety to more serious issues like asthma, COPD, heart problems, or even life-threatening emergencies such as anaphylaxis or heart attacks. While shortness of breath may sometimes occur due to exertion, pregnancy, or anxiety, persistent or sudden unexplained difficulty breathing should never be ignored. Understanding the possible causes including respiratory infections, lung disorders, physical obstruction, obesity, anemia, or panic attacks can help people recognize when to seek medical attention. Early diagnosis, appropriate treatment, and preventive steps such as avoiding triggers, exercising regularly, and managing chronic conditions are key to maintaining healthy breathing.

Bay Biosciences provide high-quality, clinical-grade matched serum and EDTA plasma samples from sepsis patients with acute respiratory failure, processed using customized protocols. Acute respiratory failure is a life-threatening condition caused by impaired gas exchange due to various underlying issues like injury, infection, or chronic disease, and requires immediate medical attention and targeted treatment.

Bay Biosciences offers high-quality, clinical-grade Atopic Dermatitis Samples, including serum and plasma biofluids, cryopreserved at -80°C. Each sample is ethically sourced and processed using customized protocols, accompanied by detailed clinical data and pathology annotations.

We support pharmaceutical and academic research by providing fully characterized human biospecimens to accelerate drug discovery, diagnostics, and dermatology research. Explore our extensive biobank of disease-specific and healthy control samples—tailored to meet your custom research needs.
