Troponin-I Test Kit Results, Normal Range, and Purpose

The Troponin-I rapid test kit is a test to detect the amount of troponin in the bloodstream. Troponin is a type of protein only found in your cardiac muscles and enters the bloodstream in case of cardiac muscle damage. This test indicates heart health and also helps in identifying any possible concerns that can manifest in the future. In this blog, we will deeply understand the working mechanism, the troponin-I test kit results, the normal range, and the purpose of the test kit. 

What is a Troponin-I Test Kit? 

The two types of proteins related to heart health are troponin-I and troponin-T. These proteins leak into your bloodstream when you are suffering from cardiac muscle damage or may suffer one in the future. Troponin-I test kits from Rosewell Remedies are highly sensitive and specific and can detect even the lowest amounts of troponin in the blood. 

This helps in the early detection of a heart attack/cardiac arrest. If you are looking for reliable, accurate, and highly precise rapid diagnostics kits, contact us.

Purpose of the Troponin-I Test 

The main purpose of this test is to identify any chances of cardiac muscle damage or manifestation of any future cardiac arrest. Some of the reasons that contribute to the spiking of troponin in the blood include other than cardiac muscle injury, 

➤ Chronic kidney disease
➤ Pulmonary embolism
➤ Congestive heart failure 
➤ Heart surgery 
➤ Heart valve disease 
➤ Irregular heart rhythms
➤ Sepsis 
➤ Exercising too much 
➤ Extreme emotional strain 

Mechanism of the Troponin-I Test Kit

The test kit works on the principle of chromatographic immunoassay. The membrane pad inside the card contains the specific antibodies that are meant to bind to this protein. When the sample is added to the sample pad, it moves across and reacts with the specific antibodies, forming a distinct line. This test is often repeated to track the levels over time. It can help the healthcare professional tailor the proper treatment plan. 

Interpretation of the Troponin-I Rapid Test Kit 

➤ Negative: When only a single line appears on the control region of the card, it indicates a negative result for high levels of troponin-I.
➤ Positive: When two lines appear on the card, one for the test region and one for the control region, it indicates a positive for the high levels of troponin-I.
➤ Invalid: When no lines are present on the card, it indicates that either the reagent has deteriorated or the test was performed incorrectly.

Normal Range for Troponin-I Test 

ResultTroponin-I Level
Normal< 0.04 ng/mL
Borderline0.04 – 0.40 ng/mL
Elevated (Abnormal)> 0.40 ng/mL

Conclusion 


The early diagnosis and treatment of heart-related disorders, particularly myocardial infarction, depend heavily on the Troponin-I test kit. Normal values help rule out acute cardiac events, whereas elevated Troponin-I levels typically indicate cardiac injury.  Purchase the highest quality rapid test kits from Rosewell Remedies, the biggest Troponin-I rapid test kits suppliers in India.
