Blood drug test

Blood drug tests are conducted to check for any traces of barbiturates or drug abuse. Blood is drawn from a vein on the inside of the elbow as is the case with other blood tests. Blood drug tests are used to screen for presence of illegal drugs or overdose or poisoning. Drug abuse of substances such as cocaine, heroin as well as overdose of amphetamines, benzodiazepines, phencyclidine and codeine can be analyzed with a blood drug test. The presence of illegal drugs or drugs not prescribed for the person indicated by a blood drug test can be suggestive of illicit drug use. Blood drug tests are conducted to monitor drug abuse cases, delirium and dementia.

Urinalysis

Routine urine analyis is done as part of regular checkup, pregnancy test or to check for UTI. Urinalysis is done along with CMP test or CBC test to get an overall picture of a person's health. Urinalyis is useful in monitoring of diabetes or endocrine disorders. It can be used to screen for drug abuse.

pH level: Typically urine pH can range from 4.5 - 8.

Specific gravity: Specific gravity of around 1.002 and 1.035 is indicative of normal kidney function.

Protein: Total protein in urine normally does not exceed 150 mg/24 hours or 10 mg/100 ml.

Glucose: Excess sugar in urine is usually indicative of diabetes mellitus.

Ketones: The presence of acetone, aceotacetic acid or beta hydroxybutyric acid can indicate caloric deprivation or any other disorder.

Septic Arthritis

Septic Arthritis is also known as bacterial arthritis and is a condition caused by bacterial infection of the joint space. The infection may be located at the affected joint or may have traveled through the bloodstream. Micro-organisms such as Staphylococcus aureus, Streptococcus pneumoniae, and group B streptococci are often the cause for this form of arthritis. This medical condition must be treated immediately lest it destroy the affected joint. The knees and hip are most often affected by septic arthritis. But sometimes the shoulder, wrist, elbow or ankles are affected. Often septic arthritis is noticed in persons who have had traumatic injury to the joint or fitted with an artificial joint. Diabetes and rhematoid arthritis can put a person at higher risk for septic arthritis. Poor immune system and intravenous drug abuse are other conditions that put a person at additional risk of contracting septic arthritis. Septic arthritis manifests with symptoms such as intense joint pain and swelling of the affected joint. Swelling on the affected joint makes it very tender and redness is noticed. Low grade fever is also noticed.

Aspiration of snyovial fluid and its culture helps in diagnosing septic arthritis. X-rays may not help in detecting this form of arthritis in the early stages. Draining the increased synovial fluid from the affected joint can help in relieving pressure and reduce symptoms of septic arthritis. The damage to the affected joint can be arrested once the fluid is drained. Blood tests can help in prescribing the right antibiotics to find the type of bacteria that is causing the infection. In the early stages of treatment, the antibiotics are directly injected into the vein. But the antibiotic treatment must be continued till the infection is completely eliminated. While warm compresses and elevation gives some relief to a person suffering from septic arthritis, rest will also do good. The affected joint may be rehabilitated with supportive exercises.
