2 Acetaminophen (N-acetyl-para-aminophenol, paracetamol, APAP) toxicity is common primarily because the medication is so readily available, and there is a perception that it is very safe
Significant overdose can result in liver failure if not promptly treated with the antidote
When is it ordered? The results of the acetaminophen test appear in micrograms per milliliter (mcg/mL): A blood level of acetaminophen in the range of 10 to 20 mcg/mL is considered safe
What is being tested? The plasma paracetamol (or acetaminophen) concentration is being measured
A blood level of acetaminophen higher than 200 mcg/mL 4 hours after ingestion means there is risk for liver damage
It is commonly included as an ingredient in cold and flu medications and is also used on its own

Peak plasma concentrations are reached in 30 to 60 minutes
ALP and GGT are interpreted together to localise the source of raised ALP in the blood:
A small amount (up to 5%) is eliminated unchanged in urine, but the remainder is metabolised in the liver (Figure 13
Oral means it's taken by mouth
People who overdose on paracetamol could be helped by a blood test that shows immediately if they are going to It depends on the type of blood test you're having

These tests are: Paracetamol - a blood test is often requested because overdoses are common and can be missed, since the affected person may have little or no symptoms
As a result, NAPQI accumulates, causing hepatocellular necrosis and possibly damage to other organs (eg, kidneys, pancreas)
Patients were then divided into 2 groups according to the result of the test: Group 1 (n=8), normal gastric emptying Plot level on paracetamol nomogram when blood resulted Take bloods 2hrs before the end of infusion 2: U&Es, HCO3, LFTs, FBC, INR, glucose and paracetamol level

The diagnosis of liver toxicity is based on serum levels of acetaminophen and other laboratory tests including liver function tests and a coagulation profile
In Management A (paracetamol level below the treatment line and an overdose <150 mg/kg), the authors suggest observation and repeat blood tests in 24 h
After NAC dosing is complete, re-evaluation of the paracetamol level and liver function tests should be done to assess if repeat dosing is
ALT <100 ALT <2x admission value paracetamol level <20 Blood tests: takes urgent bloods for U&Es, venous blood gas, LFTs, INR and FBC (should be 4 hours after ingestion) Not at risk : clinically significant hepatotoxicity is unlikely if >4 hours since last paracetamol ingestion AND paracetamol concentration <10 mg/L, ALT normal, INR ≤1
