Parkinson's Disease
You may have a shaky arm, stiff neck, balance problems, and your face may look different. But these also could be signs of a stroke, head injury, Alzheimer's disease, and even stress. There's no standard test, so it can take years to know for sure if you have it.
Neurological disease such as stroke, motor neurone disease, Alzheimer's and multiple sclerosis aren't diagnosable from blood tests. Similarly, the diagnoses of depression, schizophrenia, ADHD and autism lack a specific blood diagnostic marker.
Cancer. Cancer misdiagnosis is the most common misdiagnosed disease of all. Different types of cancers are misdiagnosed as well which is why it's important to have a complete medical history of the patient, adequate time to evaluate the patient, and complete information of symptoms and medications.
Some germs can cause asymptomatic infection, which means that the person can have the 'germ' in their body, but they don't have any symptoms of the disease or they have very mild symptoms and don't really feel sick, according to the Division of Infectious Diseases at UAMS.
Examples of invisible illnesses include myalgic encephalomyelitis (otherwise known as chronic fatigue syndrome), lupus, fibromyalgia, and Crohn's disease. Many autoimmune diseases fall under the umbrella of invisible illnesses, and several are still very misunderstood and often misdiagnosed.
cancer. dementia, including Alzheimer's disease. advanced lung, heart, kidney and liver disease. stroke and other neurological diseases, including motor neurone disease and multiple sclerosis.
When your doctor can't diagnose you, it may help to ask questions about additional testing, seek a referral to a specialist, or get a second opinion. Failure to get an accurate diagnosis can delay treatment and potentially worsen your condition.
Many diseases and infections can be asymptomatic, including those that may be potentially fatal in some people. These include (but are not limited to): tuberculosis, breast cancer, endometriosis, HIV/AIDS, herpes, hepatitis, chlamydia, hypertension, common colds/flu, and type-2 diabetes mellitus.
RPI Deficiency
This is considered to be the rarest disease in the world. Ribose-5-Phosphate Isomerase (RPI), is a crucial enzyme in a metabolic process in the human body.
In addition to detecting diseases early, blood tests help: Make a diagnosis and/or determine stages of a disease (i.e., cancer) Identify the risk of developing a disease in the future, including inherited conditions like breast cancer. Monitor organ function.
A full blood count (FBC) test looks for abnormalities in your blood, such as unusually high or low numbers of blood cells. This common blood test can help to diagnose a wide range of illnesses, infections and diseases.
Somatization is the medical term most often used for distressing physical symptoms that either cannot be attributed to a known medical condition or that seem out of proportion to it. Symptoms are a person's subjective experiences.
An idiopathic disease is any disease with an unknown cause or mechanism of apparent spontaneous origin.
Medical conditions such as diabetes, asthma, Alzheimer's and other forms of dementia, cannot be "cured," but they can be managed. In the past, medical treatment was all about treating the disease, but these days, many doctors have shifted their focus to the patient themselves, rather than just the disease.
Rabies. Rabies, one of the oldest known infectious diseases, is nearly 100% fatal and continues to cause tens of thousands of human deaths globally (1).
AIDS. Twenty-five years since it was first identified, there is still no cure for Acquired Immune Deficiency Syndrome. AIDS remains among the world's most potent killers, especially in developing countries. The disease likely started with a chimp to human jump, recent research confirmed.
A lack of awareness among physicians is one of the most common causes of medical misdiagnosis which can delay treatment. An example is when a doctor fails to recognise the symptoms of lymphedema because they have only been trained in general medicine.
But far from being definitive - a normal test result usually only indicates that your markers are within the reference range for that particular test. This reference range was made to enable doctors to quickly determine whether your body is in a crisis or there is a disease present.
A missed diagnosis happens when a patient's condition or illness is not diagnosed or addressed. This can happen for a multitude of reasons: Lack of proper medical testing. Lack of consideration of other diagnoses.
There may be few specialists or experts in a rare disease. Access to experts is limited. Diagnosis is often delayed, which delays treatment. Information and scientific knowledge about a rare disease may be lacking.
None of these tests is perfect. Sometimes false negative results occur when inflammation actually is present. False positive results may occur when abnormal test results suggest inflammation even when none is present.
