Weakness Overview
Weakness is a condition in which a person feels decrease in the strength in one or more muscles. The medical definition of weakness refers to loss of muscle strength, and conditions that can result in a measurable loss of muscle function.
Mostly the term weakness is used as a synonym for tiredness, fatigue, weariness or lack of energy. Patients suffering from certain medical conditions such as influenza, heart disease, adrenal disease, insomnia, chronic fatigue, cancer feel of overall body weakness, referring to feelings of malaise and tiredness.
Weakness may be generalized or may affect one muscle or muscle group exclusively. Diseases of the neuromuscular system, injuries, metabolic diseases, and toxins can all cause of measurable muscle weakness. Signs and symptoms of weakness can include trouble doing daily tasks, such as grooming or writing or problems with gait and loss of balance.

- Electrolytes Imbalance
- Trauma
- Thyrotoxicosis
- Malnutrition
- Muscle Disease Medications
- Muscular Dystrophy
- Myotonic Dystrophy
- Nerve Impingement
- Poisoning (Organophosphates)
- Poliomyelitis
- Malnutrition
- Congenital Myopathies (rare muscle disease)
- Drugs side effects
Signs and Symptoms of Weakness
Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens and human bio-fluid collections.
Samples available are cancer (tumor) tissue, cancer serum, cancer plasma cancer PBMC and human tissue samples from most other therapeutic areas and diseases.
Bay Biosciences maintains and manages its own bio-repository, human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and from normal healthy donors available in all formats and types.
Our biobank procures and stores fully consented, deidentified and institutional review boards (IRB) approved human tissue samples and matched controls.
All our human tissue collections, human specimens and human bio-fluids are provided with detailed samples associated patient’s clinical data.
This critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers and genetic information.
Patient’s data is extremely valuable for researchers and is used to help identify new effective treatments (drug discovery & development) in oncology, other therapeutic areas and diseases.
This clinical information is critical to demonstrate their impact, monitor the safety of medicines, testing & diagnostics, and generate new knowledge about the causes of disease and illness.
Bay Biosciences banks wide variety of human tissue samples and biological samples including cryogenically preserved at – 80°C.
Including fresh frozen tissue samples, tumor tissue samples, FFPE’s, tissue slides, with matching human bio-fluids, whole blood and blood derived products such as serum, plasma and PBMC’s.
Bay Biosciences is a global leader in collecting and providing human tissue samples according to the researchers specified requirements and customized, tailor-made collection protocols.
Please contact us anytime to discuss your special research projects and customized human tissue sample requirements.
Bay Biosciences provides human tissue samples (human specimens) from diseased and normal healthy donors which includes:
- Peripheral whole-blood,
- Amniotic fluid
- Bronchoalveolar lavage fluid (BAL)
- Sputum
- Pleural effusion
- Cerebrospinal fluid (CSF)
- Serum (sera)
- Plasma
- Peripheral blood mononuclear cells (PBMC’s)
- Saliva
- Buffy coat
- Urine
- Stool samples
- Aqueous humor

- Kidney stones (renal calculi)
- Other bodily fluids from most diseases including cancer.
We can also procure most human bio-specimens and can-do special collections and requests of human samples that are difficult to find. All our human tissue samples are procured through IRB approved clinical protocols and procedures.
In addition to the standard processing protocols Bay Biosciences can also provide human plasma, serum, PBMC bio-fluid samples using custom processing protocols, you can buy donor specific sample collections in higher volumes and specified sample aliquoting from us.
Bay Biosciences also provides human samples from normal healthy donors, volunteers, for controls and clinical research, contact us Now.
